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.

22. Small - disc-shaped bodies in the blood that play a chief role in coagulation






23. Occurs when different traits are inherited together more often than they would have been by chance along; it is assumed that these traits are linked on the same chromosome
