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 removal of an amino group from an organism - particularly from an amino acid






2. Blood protein that is transformed to fibrin upon clotting






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






4. In mitosis of higher plants - the structure that forms between the divided nuclei of the two daughter cells and eventually becomes the cell wall






5. An animal with a constant body temperature






6. A fat or oil

8. A large class of arthropods - including crabs and lobsters






9. A network of capillaries in the Bowman's capsules of the kidney






10. The recycling of carbon from decaying organisms for use in future generations






11. A disease-causing organism






12. Organelles that serve as specialized containers for metabolic reactions






13. A wall composed of cellulose that is external to the cell membrane in plants; it is primarily involved in support and in the maintenance of proper internal pressure






14. Changes in genes that are inherited






15. A fluid-filled sensory apparatus that aids balance and hearing






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






17. A nuclear protein of chromosomes that stains readily






18. A mass of cells that have similar structures and perform similar functions






19. The stable - biotic part of the ecosystem in which populations exist in balance with each other and with the environment






20. The cell body of a neuron






21. Adrenaline






22. The coagulation of blood caused by the rupture of platelets and the interaction of fibrin - fibrinogen - thrombin - prothrombin and calcium ions






23. The extraembyonic membrane of birds - reptiles and mammals that serves as an area of gaseous exchange and as a site for the storage of noxious excretion products






24. Degree of penetrability - as in membranes that allow given substances to pass through; the ability to penetrate






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






26. The production of daughter cells by means other than the sexual union of gametes (as in budding and binary fission)






27. The central tissue of a stem - used for food storage






28. The breeding of an organism with a homozygous recessive in order to determine whether an organism is homozygous dominant or heterozygous dominant for a given trait






29. A process by which the vesicle in the cell fuses with the cell membrane and releases its contents to the outside






30. A mutation involving the addition or loss of nucleotides






31. Tissue formed by the differentiation of cambium that causes a growth in width of a plant system






32. Pertaining to a subdivision of the autonomic nervous system of vertebrates






33. Daily cycles of behavior






34. A network - particularly of nerve or blood vessels






35. The extraembryonic membrane in birds - reptiles and mammals that surrounds the embryo - forming an amniotic sac






36. A stage of embryonic development in which the embryo consists of a hollow ball of cells






37. An enzyme from the pancreas that digests proteins in the small intestine






38. Movement of amoeba






39. The study of the evolutionary descent and interrelations of groups of organisms






40. Different relationships that are formed in proteins between the original sequence of amino acids and more complex three-dimensional compounds






41. The chamber in the alimentary canal of certain vertebrates located below the large intestine - into which the ureter and reproductive organs empty (as in frogs)






42. An organ centrally involved in the human digestive system






43. Partially digested food in the stomach






44. The ways in which organisms regulate their supply of water






45. The failure of some homologous pairs of chromosomes to separate following meiotic synapsis






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






47. An excretory product of protein metabolism






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






49. A substance that participates in the clotting of blood in vertebrates






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