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 grouping of neuron cell bodies that acts as a coordinating center






2. A motile - multinucleate mass of protoplasm resulting from fusion of uninuclear amoeboid cells






3. A process of photosynthesis in which water is split into H+ and OH-; the hydrogen ion is then joined to NADP






4. Daily cycles of behavior






5. The anaerobic respiration of carbohydrates






6. Globular proteins produced by tissues that destroy or inactivate antigens






7. The removal of hydrogen or electrons from a compound or addition of oxygen; half of a redox (oxidation or reduction) process






8. A specialized structure that controls osmotic pressure by removing water from the cell






9. Agent that induces mutations; typically carcinogenic






10. The orientation of cells or organisms in relation to chemical stimuli; the growth or movement response of organisms to chemical stimuli






11. The division in animal cell cytoplasm caused by the pinching in of the cell membrane






12. A plant-eating animal






13. A white or colorless - amorphous - horny substance that forms part of the outer integument of insects - crustaceans and some other invertebrates; it also occurs in certain fungi

15. An organism that is heterozygous for two different traits






16. Hormone active in osmoregulation; a mineral corticoid produced by the adrenal cortex; stimulates reabsorption of Na+ and secretion of K+






17. A type of virus that can destroy bacteria by infecting - parasitizing and eventually killing them
