Subjects : sat, science, biology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

13. A decimal fraction that represents the presence of an allele for all members of a population that have a particular gene locus






14. The hindbrain region that controls equilibrium and muscular coordination






15. The separation of some members of a population from the rest of their species; prevents interbreeding and may lead to the development of a new species
