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. A hormone that regulates water reabsorption






2. Pertaining to a type of gland that releases its secretion through a duct






3. The site of most digestion of nutrients and absorption of digested nutrients






4. The state in which two genetic traits are fully expressed and neither dominates






5. A disease-causing organism






6. The evaporation of water from leaves or other exposed surfaces of plants

8. A flowering plant; a plant of the class Angiospermae that produces seeds enclosed in an ovary and is characterized by the possession of fruits and flowers






9. The association of physical - visceral response with an environmental stimulus with which it is not naturally associated; a learned response

11. A marine biome; a region on the continental shelf that contains an ocean area with depths of up to 600 ft






12. An animal phylum in which all members have a notochord - dorsal nerve cord and pharyngeal gill slits at some embryonic stage; includes the Cephalochordata and the Vertebrates






13. The process of breaking down large organic molecules into smaller ones






14. A process of formation of ova
