Chemistry Matter and Change - Biochemistry

Chemistry Matter and Change - BiochemistryIn this final part of our look at the four disciplines of learning science in Grade 11, we'll look at a concept that's a pillar of much modern-day science teaching: biological design. In this final installment, we'll take a closer look at how biological development is taught in Chemistry Matter and Change. By the end of this, you should be well prepared to step into this topic at a later date. By the time you finish this, however, you should already be on your way to mastering the more advanced topics in Chemistry Matter and Change.The first thing you must remember about Biology Matter and Change is that the whole 'science' part of the title is simply a misnomer. All teaching material presented in this book really does fall under the category of biological science, even though there are many discussions in the book which delve into other concepts. That's fine! There's plenty of material in this book to teach all the biology topics you need to learn, especially because of the great breadth of material here.The great thing about biology is that there's plenty of good material to learn about the natural world. In Biology Matter and Change, authors P. J. W. Clark and David G. Sloman offer all sorts of content that covers many of the topics you'll find in any biology textbook, including an article from Nature covering just about every aspect of the process of biological evolution. They also provide additional articles on the same topics. Their writing style is also very clear and easy to follow, and they always end with easy-to-follow 'notes for further reading.'Biochemistry is the science that examine living things, and its literature covers a great many topics, many of which are also present in biology. Topics like DNA, RNA, proteins, and the various enzymes families will help you learn about this topic, too. Your instructors may focus more on biochemistry in their coursework, but at least one course in the class should co ver some biochemistry concepts. I think it's a good idea to supplement your biochemistry-based coursework with biochemistry-based literature when possible.Then there's 'biotechnology,' which examines the genetic material used to make everything from food to clothing. This is a fascinating subject, and it can be more challenging than biochemistry itself, but there's plenty of biotechnology literature available to help you learn about this topic. I learned about the importance of genetic engineering from the informative website Modern Life Sciences. Biotechnology is covered in different forms in Biotechnology Matter and Change, but it can easily stand alone. There's nothing else in this book, to do more than discuss biotechnology and the related subjects.Chemistry Matter and Change also provide a helpful study guide to help you develop the basic concepts that you'll need to understand all of the other topics we've discussed in this series. Students in Chemistry Matter and Change can a lso choose to purchase study guides for other chapters if they wish. So don't wait until your end-of-semester review to buy a study guide, either.Good chemistry teachers will make sure that you receive adequate material throughout your coursework, but even the best teachers will miss out on a few students who will benefit most from supplemental materials. Don't assume that supplemental material is unnecessary or unimportant! Choose a good resource and study guide and learn much more!

What to Know About College-Level Science

What to Know About College-Level Science From biotech to computer engineering, science currently ranks among the most popular academic fields among U.S. college students. If youre interested in studying science, you should know that college-level science presents both challenges and invaluable lessons that can help you prepare you for success in your field post graduation. College-level science courses will likely feel more difficult than high-school level science courses. Despite being tough, however, college-level science courses are totally plausible to succeed inall you need is a positive attitude and lots of hard work. Knowing a little about what youre getting into can be helpful as well. Heres what to know about college-level science: 1. The beginning and end of college-level science courses may be the toughest You can think of college-level science courses like a running race; if you dont get ahead in the beginning, you will be way behind by the end. College professors know this. They work hard to help ensure their students stay on top of their studies, often offering office hours and study sessions. Take advantage of these resources! That said, you cant rely completely on your college professors to get you through a college course. Its up to you to attend lectures, study for exams, and get your work done on time. Again, the beginning and end of the semesters will often be the toughest partsso be extra vigilant during these times to stay on top of your academic game. 2. Know your math for college-level science If youre majoring in a science field, youll likely be required to enroll in some math classes as well. Thats because science and math are interrelated subjects. Basic algebra is essential for studying biology and chemistry, for instance. Youll also need to learn calculus if you want to pursue physics. [RELATED: What to Know About College-Level Math] It can pay off to brush up on your math skills before the semester begins. Check out free math resources online, like MOOCs or math flashcards. You may also want to form a study group with friends who are likewise interested in improving their math skills before the start of the semester. Or, consider looking into math tutoring for help. 3. Register for your college-level science courses before other courses, if possible Most college science coursesespecially more foundational science coursesfill up quickly. Many first-time college freshmen make the mistake of waiting to add science courses to their schedules and later find it difficult or impossible to fit them in. Its especially important to take science courses in a timely fashion because higher-level science courses will likely have prerequisites (courses youre required to take before others). Avoid being closed out of the science courses you need to take by adding them to your schedule before other types of classes. Its much easier to fit lower-demand courses in your schedule than to try adding high-demand ones at the last minute. 4. Maintain endurance in college-level science by taking care of your body Science majors will often face a tough curriculum: long hours in the classroom, lab, and library are physically and mentally exhausting. Letting this kind of stress get to youis no joke and can make you very sick, so its important to continually check in with yourself throughout the semester. Consider making it a goal to achieve the following healthy habits to ensure youre taking care of yourself: Eating a nutritious diet Getting approximately eight hours of sleep each night Staying active with a sport, an extracurricular, or another activity you enjoy If you struggle to meet some of these goals, consider taking a step back and assessing what you need to change in your routine to keep yourself happy and healthy. [RELATED: How Eating Healthy Can Improve Test Scores] At times its possible to fix problems on your own, but sometimes it can be beneficial to get outside help. If its the latter case, look no further than your college campus. Colleges have great support resources available to students all day, every day, from nutritionists to recreation centers to student lounges.

A Simple Way To Expand Your Guitar Solos

A Simple Way To Expand Your Guitar Solos Suzy S. Do you feel like your fingers get locked in a box on the neck when you want to improvise on the guitar? This simple tip from guitar teacher Samuel B. will help you blow the lid off that box and start building better guitar solos At the age of fourteen, I could readily cite figures such as Eric Clapton, Stevie Ray Vaughan, and Jimi Hendrix as musical role models. I was not a child prodigy, but I maintained a pretty infectious enthusiasm for my instrument (and obviously still do). A year prior, Id been introduced to the blues scale by my eighth-grade band director and had used it in multiple rehearsal-room guitar solos. I now introduce it to my students once theyre ready to move up to the middle of the neck. There are two versions of it â€" the “clean” version (involving no more than two notes per string): E|O|||-O| B|O|||-O| G|O||O-|| D|O||O-|| A|O||O-|| E|O|||-O| and the “dirty” version (which is a little busier â€" see the two added notes): E|O|||-O| B|O|||-O| G|O||O-|-O| D|O||O-|| A|O|O-|O-|| E|O|||-O| These are both movable scales, which means you can play this shape up and down the neck starting on any fret. I will instruct you to play both versions backwards and forwards and (later) to experiment with them while I accompany you with a simple chord progression. You can also do this on your own with a recording or a looping pedal. After a while, you may find yourself unconsciously imitating patterns played by your own role models. Naturally youll want to branch out. Although enharmonic notes higher up the neck will likely prove seductive (and, yes, I play a small assortment of them in my guitar solos), Ive found it easier to play a parallel scale lower on the neck than the position where you have been playing the standard blues one: E||-X||-O|||-O| B||-X||-O|||-O| G|X|||-O||-O|-O| D|X|||-O||-O|| A||-X||-O|O|-O|| E||-X||-O|||-O| These added notes will make for a very different exercise for your left hand than standard version. For one thing, youll be using your index finger one-third as often as the bulk of movement will now be concentrated in your middle and pinkie fingers. Approach this scale delicately as it is more difficult to play than its neighboring version. After all, your index finger (thumb aside) is your strongest one. Also, dont focus on licks so much as fluidity. Take your time. Play this new combination backwards and forwards at whatever speed feels right to you. Once it has become familiar territory, youll be able to shift easily back-and-forth between both the lower scale and the higher creating twice as many possibilities for ways in which youll be able to express yourself musically.

French Grammar Rules How to Conjugate Common Irregular Verbs

French Grammar Rules How to Conjugate Common Irregular Verbs Sign up successful The conjugation of “être” is probably the two most irregular verbs in French. For “être,” it can be helpful that “estar” and “ser” are the two Spanish verbs for “to be.” Both verbs are romantic languages with Latin roots. Spanish-speakers may see the forms of both verbs jumping out at them in different present forms. For those who dont speak another romantic language already, watch as the “s” present in the Spanish verbs sneaks back into the present tense conjugation of its French cousin: Je suis Tu es Il / elle / on est Nous sommes Vous êtes Ils / elles sont The root “ser-” the second Spanish verb for “to be” comes back also in conjugating the future tense in French. For those Spanish speakers out there, keep in mind also that the accent circonflex in French (^) often indicates an -s that over centuries became silent and was then dropped. So être  was likely at one time estre, and êtes  was likely once estes â€" again, likely very familiar looking to Spanish speakers out there. The verbs “aller” and “avoir” also change forms quite a bit in the present tense: Je vais Tu vas Il / elle / on va Nous allons Vous allez Ils / elles vont J ai Tu as Il / elle / on a Nous avons Vous avez Ils / elles ont The verb “faire” becomes a bit more regular. Like most -re verbs, the -re in faire comes off and is replaced by various endings in the present tense, with the exception of the third person plural. Some of the endings corresponding with other subject pronouns also vary a little from the typical -re endings. It is worth noting that this verb really has two separate meanings â€" to make and to do. So whether you talk about doing homework or making a cake, you will use the same verb when speaking in French. Here is the present conjugation: Je fais Tu fais Il / elle / on fait Nous faisons Vous faites Ils / elles font A notable element of irregular French verbs is that they sometimes come in pairs and trios that are conjugated in the same way. The pattern for conjugating “venir” can also be applied to “tenir” (to hold) and “revenir” (to come back). Je viens / tiens / reviens Tu viens / tiens / reviens Il / elle / on vient / tient / revient Nous venons / tenons / revenons Vous venez / tenez / revenez Ils / elles viennent / tiennent / reviennent Other similar pairs include: 1) “croire” (to believe) and “boire” (to drink) 2) “voir” (to see) and “revoir” (to see again) 3) “mettre” (to put) and “remettre” (to put back) Look out for these patterns to help you categorize the irregular verbs you know, and to learn them more easily! French grammar also has two irregular verbs for to know â€" “connaître” and “savoir”. To learn more about how to conjugate irregular verbs, check out the video below. As you acquire more French vocabulary, try practicing using these verbs. For instance, talk about places you might want to go to practice the verb “aller,” or descriptions of yourself or your and friends to use the verb “être.” Then write it down, and check your spelling for each form, correcting them if necessary. You might try using one or two per week â€" because each one will take repetition and reinforcement to remember, especially with the irregularities. Remember how common they are, though. That is, after all, why they are so irregular. Even with only a few verbs, you may find there is a lot you can say!

7 Sided Polygon

7 Sided Polygon A geometric figure which is formed by 7 straight lines by joining together but the lines should not cross each other, each of two lines meet at a point and form a vertex. So 7 sided polygon has 7 sides and 7 vertices 7 sided polygon is known as heptagon. Types of polygon: - Equilateral polygon is the geometric shapes which consists of all the same sides. For example rhombus is an equilateral polygon because all sides of rhombus are equal. Equiangular polygon is the figure when all angles are same. For example rectangle is an equiangular polygon because all angles of rectangle are equal to 90 degrees. Regular polygon are those figures whose all sides and angles are equal like equilateral triangle and square are the examples of regular polygon. Formula of regular polygon Sum of interior angle= 180 x (n 2) Each interior angle = 180 x (n 2) / n Sum of exterior angle = 360 degrees Each exterior angle =360 / n Number of diagonal = n x (n -3) / 2 Number of triangles = (n 2) Where n= length of each side of a regular polygon. Question: - Find the single exterior angle of a 7 sided polygon. Solution: - Each exterior angel =360 / n = 360 / 7 = 51.43 degrees (approximately). Question 2: - Find the number of diagonals of 7 sided polygon. Solution: - Number of diagonal = n x (n -3) / 2 = 7 x (7 3) / 2 = 7x4/2 = 7x2 = 14 There are 14 diagonals in a 7 sided polygon.

Either, Neither or Too Video and Exercise

Either, Neither or Too Video and Exercise Many students in our English classes have difficulty knowing when to use either, neither or too when they want to agree or disagree with something. The words have similar meanings, but very specific uses.For example, if your friend says, I dont like sushi, if you want to agree with this statement do you say, Me neither, Me either, or Me too?Watch the video below to learn more about using either, neither and too, and then see if you can complete the exercises. Choose the correct answer below. Write your answers in comments and we will respond.1. Kevin: Do you want tea or coffee?  Freddy: _____ I will have water.a. Me toob. Eitherc. Neitherd. I dont too2. Kevin:  Do you want to go to a movie, or stay home? Freddy:  I dont care, _____ sounds nice to me.a. neither oneb. either onec. me too3. Kevin:  I dont like oysters. Freddy: _____, they are disgusting.a. Me toob. Me eitherc. Me neitherd. I dont too4. Kevin:  She loves New York City. Freddy:   _____, its a beautiful city.a. Me toob. Me eitherc. Me neitherd. I dont too5. Kevin:  Will you move to the United States or stay in Brazil? Freddy:  ____ one is possible for me.a. Me toob. Eitherc. Neitherd. I dont toOk, thanks! Contact us if you have questions. William The answers are: c, b, c, a, b. LOIEnglish Very good William. You got them all correct! Bahruz Hello! c,b,a,a,b LOIEnglish Almost Bahruz! You missed the third one. Can you see what the correct answer should be? Adolfo 4. Kevin:  â€She loves New York City.” Freddy:  â€ _____, it’s a beautiful city.” a. Me too b. Me either Could letter b be possible? LOIEnglish AdolfoWe use me too to agree with positive sentences.   For example:   Person A. I like ice-cream. Person B.  Me too.We use me neither to agree with negative sentences.   For Example:   Person A. I dont like traffic. Person B. Me neither.*Note* We use me NEITHER   me either is incorrect. Many native speakers make this mistake but technically it is incorrect. We use Either when not is in the sentence.   For example:   I dont like traffic.   I dont either.   Notice that  not + either=neither.   Adolfo So, Me either doesnt exist, right? Even in positive sentences?
