SAT Subject Test: Biology

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.
1. Tubules that excrete metabolic wastes into the hindgut in arthropods






2. A mall sex hormone (e.g. - testosterone)

15. Bacteria that are rod shaped






16. The science of classification of living things






17. One of a class of organic compounds that contains a molecular skeleton of four fused rings of carbon

19. A chemical messenger that is secreted by one part of the body and carried by the blood to affect another part of the body - usually a muscle or gland






20. Movement of amoeba






21. A jellyfish






22. 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
