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. Multicellular organism






2. Living - as in living organisms in the environment






3. The living matter of a cell - located between the cell membrane and the nucleus






4. One of a class of organic compounds that is composed of many amino acids; contains C - H - O and N






5. The diffusion of water through a semipermeable membrane - from an area of greater concentration to an area of lesser concentration






6. The passive - rhythmical expansion or dilation of the cavities of the heart (atria or ventricles) that allows these organs to fill with blood; preceded and followed by systole (contraction)






7. The transformation of an immature animal into an adult; a change in the form of an organ or structure






8. A nitrogen base that is present in nucleotides and nucleic acids; it is paired with guanine

14. A resistance to disease developed through the immune system






15. A plant that has a single cotyledon or seed-leaf






16. A gland composed of two parts - anterior and posterior - each with its own secretions; called the "master gland" because its hormones stimulate secretions by other glands






17. Process of aerobic respiration that fully harvests the energy of glucose; also known as the citric acid cycle






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






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






20. A relationship in which one organism benefits at the expense of another

22. Occurs when a segment of genetic material on a chromosome becomes reversed






23. Cytoplasmic organelles that serve as sites of respiration; a rod-shaped body in the cytoplasm known to be the center of cellular respiration
