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






2. The instance of polymorphism in which there is a difference of form between two members of a species - as between males and females






3. A hormone produced by the Islets of Langerhans in the pancreas






4. The smallest particle that is capable of carrying out photosynthesis; the functional unit of a chloroplast






5. An abbreviation of nicotinamide-adenine-dinucleotide-phosphate - also called TPN; an organic compound that serves as an oxidation-reduction molecule






6. An accumulation of axons within the CNS that is white because it is fatty - myelin sheath






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






8. A perforation leading from the pharynx to the outside environment that is a characteristic of chordates at one stage of their development






9. Movement of amoeba






10. The study of form and structure






11. One of the two strands that constitute a chromosome; chromatids are held together by the centromere






12. Undifferentiated tissue in the stem of a plant that aids growth in width






13. An embryonic structure that gives rise to the central nervous system






14. A bony or chitinous case or shield covering the back or part of the back of an animal (shell of a crab)






15. Agent that induces mutations; typically carcinogenic






16. A hydrogen carrier containing iron that functions in many cellular processes - including respiration






17. The place of attachment of the mitotic fiber to the chromosome






18. 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






19. An organelle that regulates cell functions and contains the genetic material of the cell






20. One of the paired lateral divisions of the forebrain






21. Blood vessels located between ascending and descending aortas that deliver blood to most of the upper body
