Organic Chemistry Definition - What Is Molecule?

Organic Chemistry Definition - What Is Molecule?The organic chemistry definition of the word 'element' has to do with all the things in the universe that are not solid or liquid. While this may seem a bit contradictory, the reality is that there are actually many examples of things that may seem solid and that could be considered elements, but they are composed of atoms instead of the more typical compounds.The second most important fact about molecules is that it can be broken down into smaller particles with great ease. It is this ability to split a molecule that makes it so effective as a form of energy storage. A cell can utilize molecules as a way to store large amounts of energy, and this is what is so attractive about them.The DNA of a cell absorbs electrons when it divides, and this allows for molecules of some elements to become charged. This allows the molecules to combine with one another, which creates an electron, which is then dispersed throughout the body. The good par t about this is that this electron can be used for a variety of different functions and to help push molecules around in the body.There are also several rare elements in the world that are known to aid in the creation of new molecules, as well as in the containment of some existing ones. The reason for this is that when they are found, they are useful for other things. It is thought that a handful of these rare elements could actually be on the outermost fringes of our galaxy, but are not detectable with modern science.There are three major types of molecules, which can be broken down into smaller ones, along with oxygen, nitrogen, carbon, and hydrogen. When you break down these five parts, you find that each of them have their own different characteristics. These are all examples of the atoms of the standard chemical reactions, which are essential to the functions of every cell in the body.Molecules are by far the largest element that our bodies contain. They also are the strongest , which is why they are extremely resilient to disruption and damage. As the name suggests, they are the primary reason that all the other elements exist.A substance that is capable of modifying itself, with its ability to combine with another molecule, is referred to as a polymer, and there are many different types of this. For example, proteins are in fact a polymer, while cells are not.Some of the things that the cells need in order to survive are hydrogen, oxygen, nitrogen, carbon, and silicon, and all of these elements are necessary for the cells to function. Not only that, but there are some very complex reactions that a cell needs to take place, as well as the proteins necessary for the process. There are also different types of chemical reactions that a cell can carry out that enable it to accomplish its jobs.

What is the Year 1 Phonics Test

What is the Year 1 Phonics Test We all know how important it is for children to learn literacy. And early learning of the phonics has become a very important part of a child's reading journey. The Phonics Screening test was first launched by the Department of Education in June 2012 and schools will administer the test the week beginning 13 June for this year. The test is defined by the Department of Education as short, light-touch assessments that usually take between four and nine minutes for each child to complete. The Phonics Screening Check The Phonics test or Phonics screening check is compulsory for all year 1 children and is used to determine whether they have learnt phonic decoding to the proper standard. It identifies children that may need extra help in improving their reading skills and allows the school to step in and make sure these children meet the appropriate standard. The test itself consists of a list of forty words which the children read to a teacher and tests the ability to use letter-sound knowledge to correctly read and pronounce written words. The words used are twenty real-words and twenty non-words (made-up words). The reason for the non-words are so that there will not be a bias to those children with a good vocabulary. The non-words are shown alongside a picture of a fictional character and the children are told that the non-word is the name of that fictional creature or character allowing children to understand that the non-word should not be included in their existing vocabulary. Children who are able to read non-words should have the skills to decode most unfamiliar words. Phonics knowledge is taught to children from Reception class helping them to recognise and read familiar words and to be able to read words that are completely new to them. They learn about the way graphemes (written words) relate to phonemes (spoken words) and how to sound out the words. The International phonetic alphabet The following table shows the International Phonetic Alphabet that is used to explain the pronunciation of pseudo-words used in the Phonics Screening check for year 1 children (words that are not included in the test are in red whilst the words in blue indicate that the grapheme-phoneme correspondence only applies to certain regional pronunciations): Consonants Vowels Phoneme Example Phoneme Graphemes /b/ bad /??/ father, arm /d/ dog /?/ hot // this // cat /d?/ gem, jug /a?/ mind, pie, high, fine /f/ if, puff, photo /a?/ out, cow /g/ gum /?/ hen, head /h/ how /e?/ say, came, bait /j/ yes /??/ air /k/ cat check, key, school /??/ cold, bone, coat, mould, blow /l/ leg, hill /?/ hit /m/ man /??/ beer /n/ man /i?/ he, bead, see, scheme, chief /?/ sing /??/ launch, raw, born // both /??/ coin, boy /p/ pet /?/ book, cup, could /r/ red /??/ tour /s/ sit, miss, cell /u?/ stew, room, you, blue, brute /?/ she, chef /?/ cup /t/ tea /??/ fern, turn, girl /t?/ check /?/ farmer /v/ vet /w/ wet, when /z/ zip, hens, buzz /?/ pleasure Source: satpapers.org The Threshold and results In 2012 when the first testing began the threshold was 80% and continues to be around this mark. This means that children need to correctly identify and read 32 words out of the total 40 words to be considered to have met the necessary standard. The test determines whether children are correctly able to identify sounds associated with different letters, and letter combinations, and consequently blend these sounds together to correctly say the word on the list, regardless of whether the word is a real-word or a non-word. The combinations of the letters become more complicated as they move down the list of words meaning the words become increasingly harder. The threshold mark is conveyed to schools usually at the end of June so that teachers can then mark the test. Parents are then informed of how their child did although the results are not published. If a child fails to meet the standard they are given extra help in their phonics understanding and can then retake the test in year 2. What can you do to help? The best way to ensure your child will meet the standards of the phonics screening check is to enhance their vocabulary. Read new books with them and introduce them to new vocabulary. Play word games with them and make sure they are correctly sounding out the words. There are plenty of free resources for practising phonics with your child; the Schoolrun website offers some great information and the Department of Education website offers more information and some practice assessments. A private tutor can also be a great help in aiding your child's learning of the phonics.

Why You Should Take A Hot Bath

Why You Should Take A Hot BathHot water baths are not so unlike cold baths. And that's good news because they can be used to lower your cholesterol and lower your blood pressure. The reason they are used to help in these two areas is because of the different chemical changes when heated water enters your system. That has been scientifically proven by research over the years.At the time when you take a warm shower or take a hot bath, you are using a lot of heat to get you through the day. But, when you take a warm bath, you don't use as much heat. That's why taking a warm bath can lower your blood pressure much more than you could possibly imagine.In fact, a lot of the medical research about lowering your cholesterol using hot water has shown that after you take a warm bath, your body is able to make a couple of molecules of dihydrotestosterone (DHT). DHT is a hormone that is known to be linked to heart disease.When you use hot water in a hot bath, the dihydrotestosterone can be flush ed out of your body and the chemicals in your blood are cleaned. When it comes to cleaning your body, your blood vessels are probably the first thing that come to mind.Because your blood vessels are clean, they are now getting better oxygen as well as nutrients. Oxygen and nutrients to help in your fight against those nasty molecules that contribute to your cholesterol issues. The substances in the hot water helps clean out those cells that are clogging your arteries.After you take a hot bath, your body also becomes cleaner and more efficient at removing those impurities that may have settled on your skin. These impurities are now helping the body get the blood it needs to run efficiently. If your body has all the nutrients it needs to heal itself, then you are less likely to experience muscle cramps or other types of problems.So if you are thinking about taking a hot bath or shower, try to do it right after a nice meal. That will help your body to flush away the impurities and it w ill cleanse you of the cholesterol you have.

Podcast For Beginners - Do You Start With Podcasts For Beginners?

Podcast For Beginners - Do You Start With Podcasts For Beginners?I have a big problem with people who only start with Podcasts for beginners. It is completely the wrong thing to do.The first thing you need to learn before you can be successful at anything is your fundamental skills. Without this, you can't even get by in the world of work. That is why everybody always looks for somebody else to teach them something new. And because they can't afford to hire someone else, they go to a person who can teach them something that is free.So, when it comes to your Podcast for beginners, make sure that you first learn some of the basics of the language that you want to learn. If you don't, there is no way that you will be able to overcome the language barrier that you are going to face and the problems that you are going to face in the future.But, even if you want to put that skill into practice, make sure that you understand how to put it into action. That is not possible if you just go to the computer and click the button that tells you what you want to hear.Make sure that you take the time to look for some of the basic language lessons that you can find online, and listen to them. This will give you a feel for what it feels like to speak fluently and make you realize that you have a lot of ground to cover.These podcasts for beginners also need to make you realize that you don't have to be an expert in order to improve your understanding of the language. There are certain basics that you have to get used to.I hope you found this article helpful. You need to make sure that you keep a full head start on everything.

How to Get Started With Cell Biology Lectures

How to Get Started With Cell Biology LecturesWhat is Cell Biology? Cell Biology is a branch of Biology that deals with the structure and behavior of cells. We know that cells are in every living thing, but not everything we know about cells comes from the study of cells. Cell Biology is the study of all the structures and functions of living cells.Cell physiology: This one is pretty self explanatory. You will learn the different types of cells in the body, how they work, and how you can use this knowledge to help treat illnesses and improve our quality of life. You will also learn about the structures of the different cell types, which in turn will allow you to develop a better understanding of how to make them more efficient. In fact, some very successful pharmaceutical companies were started by scientists who focused on developing new drugs and drug treatments using cell structure as part of their success.Tissue culture: If you want to know more about Cell Biology, this is where yo u start. While Cell Biology is very detailed, it still relies on the study of cells as well as their different abilities. This means that any knowledge that can be learned from this area will be useful.Molecular Biology: When you get to Molecular Biology, you will learn all the molecular secrets of the body. This includes studying how various proteins interact and how this relates to the body and how the body's health is affected by the interaction of various proteins.Bioinformatics: This is where you learn about genetics, physiology, anatomy, and the formation of organs. In addition to this, you will learn how to use this knowledge to take advantage of these tools to help you diagnose diseases, manipulate cell line cultures, and build new tools that can help with research.Bioinformatics is the study of everything from gene regulation to cell biology, and the way the information about cell biology that is being used in these fields relates to each other. In fact, the scientific comm unity is increasingly focusing on this field as an area that needs more attention.To get a good grasp of Cell Biology, you need to get a good education in biology. Getting a bachelor's degree is usually your best bet, but if you cannot afford a lot of time and money, you may consider getting a PhD in Cell Biology or a MS in Cell Biology in order to specialize in your career.

My Experience at University of California, Davis

My Experience at University of California, Davis The tutors behind Varsity Tutors are not just here to teachtheyre sharing their college experiences as well. Jason earned his bachelors degree in Spanish from University of California, Davis in 2010. Currently based in San Francisco, he specializes in many levels of Spanish tutoring. Check out what he had to say about his time at University of California, Davis: Describe the campus setting and transportation options. Jason: UC Davis has a great location California. I felt safe, even late at night, because there is a lot of security and transportation assistance. While I made sure I found apartments close to campus and biked everywhere (its known as a bike town, and is especially great for biking because its so flat), most of my friends took the bus and managed fine. It comes every 20-30 minutes to most areas of Davis from 7AM to around 10PM. The campus is more rural than urban; however, Sacramento, the capitol of California, is 20-30 minutes northeast and is a great urban city. How available are the professors, academic advisers, and teaching assistants at University of California, Davis? Jason: While this depends largely on your major, I had a great experience at UC Davis studying my double major of Spanish and Psychology. I attended many office hours for many professors, which is partly why I got such strong grades. The academic advisers care too and are very approachable and available for appointments, so use them as resources. Make appointments earlier rather than later so you graduate on time and can plan effectively. All the teaching assistants were great too; they were qualified and helpful for exams. They are usually PhD students, which is what I am now at University of Georgia. How would you describe the dorm liferooms, dining options, location, socialization opportunities with other students? Jason: Dorm life is very fun at Davis. I made many friends my first-year in my dorm and remained friends all four years.The dining commons are great; clean, close-by, and relatively affordable, with a lot of options. Most dorms host many events for students to socialize. Which majors/programs are best represented and supported? Jason: I always knew I wanted to help people and become a therapist. Two years into it, I discovered it was very competitive and difficult to get internships and extracurricular training opportunities, so I decided to learn Spanish and double-major to make myself more marketable. I chose to major in Spanish because I loved the culture and language. There are also progressively more and more Spanish-speaking people in the U.S. who need mental health services and theres a significant dearth of bilingual health professionals. The only issue with the psychology major at UC Davis is that the introductory classes are quite large, and primarily research-focused not clinical. How easy or difficult was it for you to meet people and make friends as a freshman? Does Greek life play a significant role in the campus social life at University of California, Davis? Jason: I honestly did struggle the first couple of months, feeling lonely, homesick and a little out-of-place. After a few months, however, I realized there are so many great people to meet, so I started to really enjoy myself and develop meaningful friendships. I wasnt into Greek life, but I know many people who had great experiences with it. Its very popular at UC Davis. How helpful is the Career Centerand other student support services? Jason: I liked the Career Center at Davis I just regret not using it more often to help with graduate school applications. There are many other student support services to take advantage of as well. How are the various study areas such aslibraries, the student union, and dorm lounges at University of California, Davis? Jason: At first glance, UC Davis may seem over-crowded, but there are many areas to study and explore. The first floor in the library at Davis may be crowded during finals week, but the upper floors are empty and great to study if you thrive on silence. The student union looks crowded too, but it has its spots as well. Describe the surrounding town. Jason: While I didnt leave campus much because I was studying and happy with the many on-campus activities, I know Sacramento has a lot to explore. There are many great places to hike, streets to explore, and sights. Its a cute little town with many great restaurants and booming nightlife. How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Jason: In psychology, as noted above, I wished most of my classes were smaller so there would have been more dialogue and attention with professors. They did get smaller, however, as I advanced to more upper-level classes. In Spanish, the classes are smaller since there are less students, so I was happier there. While not so much in Spanish, a bigger problem in the Psychology major was getting into classes. A few times the class I wanted or needed filled up before I could register, which was a little disappointing. Psychology is such a popular major, however, that as you advance through the major, your enrollment appointments become earlier, making this less of an issue. Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Jason: I loved my advanced Spanish grammar class with Dr. Charles Oriel. He is the coolest professor and is insanely knowledgeable about Spanish grammar and vocabulary. He also makes it fun. I attribute a lot of my success and command of the language to him. I also studied abroad twice, three months in Mexico and seven months in Costa Rica, as part of my Spanish major. I loved Latin America and had so much fun. The most difficult part was struggling in the advanced literature course at the University of Costa Rica. Even though I had only been learning Spanish for two years at the time, the professor treated me like a native Costa Rican student with the same standards. Now my Spanish is almost native and reflects extensive language education and training. Check out Jasons tutoring profile.

What is it Like to Attend Tufts University

What is it Like to Attend Tufts University The tutors behind Varsity Tutors are not just here to teach theyre sharing their college experiences as well. Evelyn is a St. Louis tutor specializing in SAT prep tutoring, GRE prep tutoring, Middle School Math tutoring, and more. She graduated from Tufts University in 2009 with a degree in Biopsychology. See what she had to say about her alma mater: VT: Describe the campus setting and transportation options.How urban or safe is the campus?Are there buses or do you need a car/bike? Evelyn: Tufts University is located in Somerville/Medford, right outside of Boston. I really liked that the school is located in a less busy, suburban area but is still close to the city. I felt safe on the Tufts campus, but I always used common sense strategies just in case (e.g., didnt walk around alone at night, paid attention to my surroundings). There is a lot of public transportation available for Tufts students, including bus and subway systems. In addition, Tufts runs a campus shuttle (known as The Joey) that can transport you to a few different locations on-campus. It also goes to Davis Square, the location of the nearest subway stop (about a 15-20 minute walk away from campus). I dont think its necessary to have a bike or car at Tufts, though it can make it easier to get to certain places a little further from campus (e.g., the grocery store, Target). VT: How available are the professors, academic advisers, and teaching assistants? Evelyn: I never had an issue with getting in touch with professors, academic advisers, teaching assistants, etc.everyone that I had was very accessible, both via e-mail and to meet in-person. Most of my professors and teaching assistants actually encouraged students to reach out to them, which I dont think is always the case at other schools. VT: How would you describe the dorm life rooms, dining options, location, socialization opportunities with other students? Evelyn: All freshmen and sophomores are required to live in dorms on-campus. Students can choose from various dorm options (e.g., different locations on campus, healthy living, freshmen-only, suites or individual rooms, etc.). Some dorms are better than others, but theyre all passable. There isnt enough on-campus housing for everyone at the school, so it can be little difficult to get a dorm as a junior or senior. There are a lot of apartments available for rent right next to the campus, though, and I was actually ready to live in my own place by the time I was a junior! There are two main dining halls on-campusI got a little tired of the food by the time I was a senior, but it was still pretty good overall. Tufts Dining Services makes a conscious effort to offer a variety of foods, including healthy options, and the dining halls had some fun theme nights every week (I remember stir fry night being particularly popular at one of the dining halls). The school is actually in both Somerville and Medford, two towns right outside of Boston. I really liked the location because it was still pretty close to the city without being right in the middle of it. There were a lot of opportunities for socialization on-campusI met most of my friends through running cross-country and track, but there are a ton of other groups students can join (intramural sports, various music groups, fraternities and sororities). A lot of my friends were also really close with people they met in their freshmen dorms. VT: Which majors/programs are best represented and supported?What did you study and why? Did the university do a good job supporting your particular area of study? Evelyn: Tufts undergraduate program is divided into the School of Arts Sciences and the School of Engineering. When I was a student, I knew a lot of people who majored in English, Economics, Biology, Psychology, and International Relations, and several of my friends were Engineering majors. I was a Biopsychology major, so I took classes in both the Biology and Psychology departments. Ive always been interested in the biological basis of cognition and behaviour, so that major was a perfect fit for me. I felt very supported in my studiesI had a great adviser and some really amazing professors. VT: How easy or difficult was it for you to meet people and make friends as a freshman? Does Greek life play a significant role in the campus social life? Evelyn: It was pretty easy for me to meet people as a freshman because I was a member of a sports team. It seemed like it was relatively easy for most people on-campus to make friends, though, either through their dorm or some type of student group. When I was in school, Greek life didnt play a huge role on-campus, but they did have a presence. I wasnt involved in the Greek system at all, but I remember hearing a lot about various philanthropic activities they were involved in (as well as parties they would host on the weekends!). VT: How helpful is the Career Centerand other student support services?Do many reputable companies recruit on campus? Evelyn: I found Tufts Career Center very helpful, especially when I was applying to Teach for America my senior year. I know they offer help with resumes and cover letters, hold various career fairs, and assist people in applying for graduate school and jobs. The Academic Resource Center was also a really great serviceI worked there as a biology and psychology tutor, but I know they offer tutoring in virtually all subjects. Tufts is well-known as an academically rigorous school, so I think a lot of reputable companies recruit on-campus. VT: How are the various study areas such aslibraries, student union, and dorm lounges? Are they over-crowded, easily available, spacious? Evelyn: The on-campus study areas were easily available and spacious, for the most part. The only time it may have been hard to find a place to study at the library was during finals period, if you didnt get there pretty early in the morning. VT: Describe the surrounding town. What kinds of outside establishments / things to do are there that make it fun, boring, or somewhere in between?To what extent do students go to the downtown area of the city versus staying near campus? Evelyn: There is a lot going on in the Boston arealots of museums, concert venues, shopping, great restaurants! Davis Square is about a 15-20 minute walk away from campus, and it has a few good bars and places to eat (and a delicious ice cream placeJP Licks). From there, its a pretty short subway ride to Cambridge and Boston. In my experience, most people at Tufts usually stayed relatively close to campus (e.g., Davis or Harvard Square). It could take anywhere from 30 minutes to an hour to get to downtown Boston, depending on where you wanted to go. People would venture into the city every now and then, though, especially when there were special events going on (Head of the Charles Regatta, St. Patricks Day Parade, Boston Marathon). VT: How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Evelyn: The undergraduate student body is about 5,000 people. I was, for the most part, pleased with the class sizesexcept for a few introductory courses I had to take for my major, classes were usually pretty small (about 15 people per class). VT: Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Evelyn: My most memorable experience was, in the summer before my senior year, participating in a program called Research for Undergraduates. I got to do an independent research project about sexual selection in fireflies (I could nerd out right now, but I wont. Ill just say that it was very interesting!). Everyone in the program got to do his or her own project and present the findings at a research symposium at the end of the summer. We also went on a couple biology-related field trips and had weekly meetings/seminars about various topics in biology. It was a memorable experience because I had an awesome mentor and got to investigate a topic I found fascinating. I worked hard on my project and got a lot out of it (including a paper published in a scientific journal, which Im still really proud of!). Check out Evelyns tutoring profile.
