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. Waves of contraction and relaxation passing along a tubular structure - such as the digestive tube






2. Any cell capable of ingesting another cell






3. A sensory organ capable of detecting light






4. Any organism that is the victim of a parasite






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






6. A fatty sheath surrounding the axon of a neuron that aids in stimulus transmission; it is secreted by the Schwann cells






7. An organism that does not require free oxygen in order to respire






8. A transmitter substance released from the axons of nerve cells at the synapse






9. A cell in the retina that is sensitive to colors and is responsible for color vision






10. A ductless gland in upper chest region concerned with immunity and the maturation of lymphocytes






11. A complex carrier mechanism located on the inside of the inner mitochondrial membrane of the cell; releases energy and is used to form ATP






12. Genetic blending; each allele exerts some influence on the phenotype






13. The exchange of parts of homologous chromosomes during meiosis






14. A mitotic stage in which nuclei reform and nuclear membrane reappears






15. The living together of two organisms in an intimate relationship

17. Semen






18. Pertains to a gene or characteristic that is masked when a dominant allele is present






19. The small granular body within the centrosome to which the spindle fibers attach






20. 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






21. A hormone that regulates water reabsorption






22. Adenosine diphosphate (ADP) and adenosine triphosphate (ATP) - which are energy storage molecules






23. The biome located between the polar region and the tiaga






24. Pertaining to a restricted locality; ecologically - occurring only in one particular region






25. Anaerobic respiration the yields 2 molecules of ATP - lactic acid - ethyl alcohol and carbon dioxide or some similar compound via the glycolytic pathway






26. The process by which a certain function is regulated by the amount of the substance it produces






27. A flexible - supportive rod running longitudinally through the dorsum ventral to the nerve cord; found in lower chordates and in the embryos of vertebrates






28. The inner layer of an organ surrounded by the cortex






29. A network - particularly of nerve or blood vessels






30. The hindbrain region that controls equilibrium and muscular coordination






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

36. A bundle of nerve axons






37. The process by which carbohydrates are formed through chemical energy; found in bacteria






38. A cell in the retina that is sensitive to weak light






39. A portion of the CNS consisting of cytons (cell bodies) - their dendrites and synaptic connections






40. Chemical groups attached to carbon skeletons that give compounds their functionality






41. One of the paired lateral divisions of the forebrain






42. The portion of alimentary canal in which some protein digestion occurs






43. Describes structures that have similar function but different evolutionary origins; e.g. - a bird's wing and a moth's wing
