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 ability to respond to a stimulus






2. A mall sex hormone (e.g. - testosterone)






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






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






5. A pouched mammal - such as the kangaroo or opossum






6. The large intestine






7. A response by an organism to the duration and timing of light and dark conditions






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






9. The navel






10. Outgrowths of a root's epidermal cells that allow for greater surface area for absorption of nutrients and water






11. A plant-eating animal






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






13. The fluid that remains after fibrinogen is removed from the blood plasma of vertebrates






14. Nonfunctional haploid cells created during meiosis in females; they have very little cytoplasm-most has gone into the functional egg cell






15. The process by which environmental patterns or objects presented to a developing organism during a "critical period" of its growth is accepted as a permanent element of its behavior






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






17. A mature ovary






18. Unicellular organism with simple cell structure






19. Functional urinary tubules responsible for excretion in the kidney of vertebrates






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






21. A marine biome; a region on the continental shelf that contains an ocean area with depths of up to 600 ft






22. A substance that is acted upon by an enzyme






23. In taxonomy - a classification between species and family






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






25. A constituent of the plasma of the blood of vertebrates; it is converted to thrombin by thrombokinase in the presence of calcium ions - thus contributing to the clotting of blood






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






27. The basal branch of each spinal nerve; carries motor neurons






28. Related to the sense of smell






29. A progressive change from which a permanently more mature or advanced state results






30. Daily cycles of behavior






31. The dorsal part of the hip girdle






32. A decimal fraction that represents the presence of an allele for all members of a population that have a particular gene locus






33. 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)






34. Laws of classical genetics established through Mendel's experiments with peas






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






36. The external opening of the trachea in insects






37. A chemical messenger that is secreted by one part of the body and carried by the blood to affect another part of the body - usually a muscle or gland






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






39. A network or mesh of fibrils - fibers or filaments






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






41. A blood clot that is formed within a blood vessel






42. A microscopic opening located in the epidermis of a leaf and formed by a pair of guard cells






43. The uppermost portion of pistil upon which pollen grains alight






44. A lymph tubule located in the villus that absorbs fatty acids






45. The largest portion of the human brain; it is believed to be the center of intelligence - conscious thought and sensation






46. A 12-carbon sugar that is formed by the union of two glucose units (a disaccharide)






47. An organ that is not functional in an organism - but was functional at some period in its evolution






48. Pertaining to a subdivision of the autonomic nervous system






49. The ability of an organism to contribute its alleles and therefore is phenotypic traits to future generations






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