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






2. The enzyme released from the blood platelets in vertebrates during clotting






3. The transfer of pollen from the stamen to the pistil of the same flower






4. 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






5. Pertaining to the head






6. One of the paired lateral divisions of the forebrain






7. The swelling at the end of an axon






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






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






10. The space between the mesodermal layers that forms the body cavity of some animal phyla






11. A plant growth hormone






12. A lateral region of the forebrain






13. A specialized structure that leads to the digestive tract of a developing organism and provides it with food during early development






14. A hormone of the thyroid that regulates basal metabolism






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






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






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






18. Describes an individual that possesses two contrasting alleles for a given trait






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






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






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






22. A green pigment that performs essential functions as an electron donor and light "entrapper" in photosynthesis






23. 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






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






25. A dark-staining small body within the nucleus; composed of RNA






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






27. A specialized structure that carries out particular functions for eukaryotic cells






28. Random evolutionary changes in the genetic makeup of a population






29. Any cell capable of ingesting another cell






30. An organism that obtains its nutrients from dead organisms






31. An animal with a constant body temperature






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






33. Small - disc-shaped bodies in the blood that play a chief role in coagulation






34. 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






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






36. Any cell that is not a reproductive cell






37. A purine (nitrogenous base) component of nucleotides and nucleic acids; links with cytosine in DNA






38. Pertaining to a type of gland that releases its secretion through a duct






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






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






41. The type of mating that occurs when an organism selects a mating partner that resembles itself






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






43. The female gonad in animals; the base of the pistil in plants






44. A stage of mitosis; chromosomes line up at the equator of the cell






45. An organism that is heterozygous for two different traits






46. The thin - bent part of the renal tubule that is the site of the counter-current flow and the sodium gradient






47. A mature ovary






48. The outer - transparent layer of the eye






49. A compact linear organization of nerve tissues with ganglia in the CNS






50. A starch form in animals; glucose is converted to this in the liver
