Mathematical Biology. 13: Lotka Volterra Competiton
Although not all colleges and universities require SAT subject tests for admission, some do require them for specific majors or offer course credit if you score well enough. These tests are also useful for assessing your knowledge of science, math, English, history, and languages. The College Board offers subject tests in three scientific categories : chemistry, physics, and biology. Biology is subdivided into two categories: biology ecology, known as Biology-E, and molecular biology, known as Biology-M.
They are two separate tests, and you cannot take them both on the same day. Questions on both the Biology E and M exams biol e potenza divided evenly between fundamental concepts: identifying biol e potenza and definitions, interpretation analyzing data and drawing conclusionsand application solving word problems.
The College Board recommends students take the Biology E test if they are more interested in biol e potenza such as ecology, biodiversity, and evolution. Students more interested in topics such as animal behavior, biochemistryand photosynthesis should take the Biology M exam. It's also a good idea to check with your college admissions officer to confirm whether or not these tests are required.
The Biology E and M tests cover five categories. The number of questions on each exam varies according to the topic. Experts at the Princeton Reviewan established test-prep organization, biol e potenza you should begin studying at least two months before you plan to take an SAT subject test.
Schedule regular sessions each week for at least 30 to 90 minutes, and be sure to take breaks as you study. Many of the major biol e potenza companies offer free sample SAT subject tests.
Use these to evaluate your skills before you begin studying and at least a couple times prior to taking the actual exams. Then, check your performance against the average scores provided by the College Board. All of the major test-prep companies also sell study guides, offer classroom and online review sessions, and provide tutoring options. Be aware that the price for some of these services can cost several hundred dollars. Standardized tests like the SAT are designed to be challenging, but with preparation, you can succeed.
Here are some tips biol e potenza testing experts recommend to help you get the best scores possible:. The answer B is correct. The woman of 40 with seven adult offspring has left the most surviving offspring and is the most fit evolutionarily. Which of the following most accurately reveals common ancestry among many different species of organisms?
Answer A is correct. To assess common ancestry among organisms, differences biol e potenza similarities in homologous structures are studied. Differences in homologous structures reflect the accumulation of mutations over time. The only choice listed that biol e potenza a comparison of a homologous structure is choice A. Cytochrome C is a protein that can be studied, and its amino acid sequences compared.
The fewer differences in the amino acid sequence, the closer the relationship. Share Flipboard Email. Here are some basics you should know about the Biology E and M tests:. Each test is timed, biol e potenza 60 minutes, and contains 80 multiple-choice questions. Scoring ranges from to points in total.
Calculators may not be used for the exam, except for Math 1 and Math 2 tests. The metric system is used for all measurements biol e potenza test questions. The College Board recommends having at least one year of college-prep biology, plus a year of algebraand experience in a classroom laboratory setting. Cellular and molecular biology Biology E, 15 percent; Biology M, 27 percent : Cell structure and organization, mitosis, photosynthesiscellular respiration, enzymes, biosynthesis, biological chemistry.
Schedule tests, particularly science and math, for as soon as possible after you've finished your relevant high school coursework. This way, the knowledge will be fresh in your mind. Register early biol e potenza you'll be able to take the test well ahead of when results are due for college admissions. Confirm your admission status. Whether you register online or by mail, you'll receive an "admissions ticket" that lists your test time, location, and date. Check to biol e potenza sure all the info is correct; if not, call the College Board.
Make sure you have the right test materials. You'll need to bring your admissions ticket to the testing site to confirm your registration. You'll also need a photo ID, as well biol e potenza two No. Pace yourself. Remember, you only have 60 minutes to complete the exam. Do the easy questions first, then circle back to those that challenge you. If you find yourself running low on time, don't be afraid to make an educated guess on questions that you're stuck on.
Get plenty of rest the night before. Tests like the SAT are intellectually demanding. You'll want to be fresh and alert when you take the tests. Which of the following individuals is most fit in evolutionary terms? A A child who does not become infected with any of the usual childhood diseases, such as measles or chicken pox. B A woman of 40 with seven adult offspring.
C A woman of 80 who has one adult offspring. D A year old man with no offspring. E A childless man who can run a mile in less than five minutes.
A The amino acid sequence of their cytochrome C. B Their ability to synthesize hemoglobin. C The percentage of their body weight that is fat. D The percentage of their body surface that is used in gas exchange.
E The mechanism of their mode of locomotion. Franek, Rob. Continue Reading.
