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 navel






2. Substance secreted by organisms that influences the behavior of other members of the same species






3. Fluid-filled structures in the inner ear that are associated with the sense of balance






4. The outermost - extra-embryonic membrane of reptiles and birds






5. A process by which the cell membrane is invaginated to form a vesicle which contains extracellular medium






6. A process of cell division whereby each daughter cell receives only one set of chromosomes; the formation of gametes






7. xylem that is no longer being used






8. Asexual reproduction; in this process - the parent organism splits into two equal daughter cells






9. A chemical action that releases energy from glucose to form ATP






10. The evaporation of water from leaves or other exposed surfaces of plants






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






12. The thin-walled anterior chamber of the heart (also called the auricle)






13. Self-digestion occurring in plant and animal tissues - particularly after they have ceased to function properly






14. A mutation in which a single nucleotide base is substituted for another nucleotide base - or an extra nucleotide base is added






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






16. A resistance to disease developed through the immune system






17. A section of the posterior forebrain associated with the pituitary gland






18. The portion of alimentary canal connecting the pharynx and the stomach






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






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






21. An organism that utilizes the energy of inorganic materials such as water and carbon dioxide or the sun to manufacture organic materials






22. 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






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






24. A symbol that denotes the relative concentration of hydrogen ions in a solution






25. An excretory product of protein metabolism

27. A colloidal system involving the dispersion of a liquid within a liquid






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






29. Protein threads that form in the blood during clotting






30. The phylum of sponges






31. The kind of bond formed when two amino acid units are jointed end to end






32. The part of the flower that produces pollen






33. The part of the nervous system that regulates the involuntary muscles - such as the walls of the alimentary canal; includes the parasympathetic and sympathetic nervous systems






34. Describes arthropods and other animals whose skeletal or supporting structures are outside the skin






35. The dorsal part of the hip girdle






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






37. A hormone that regulates water reabsorption






38. The part of the neuron that transmits impulses to the cell body






39. The state in which two genetic traits are fully expressed and neither dominates






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






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






42. A nitrogenous base such as adenine or guanine; when joined with sugar or phosphate - a component of nucleotides and nucleic acids






43. The primary germ layer - developed from the lip of the blastopore - that gives rise to the skeleton - the circulatory system and many organs and tissues between the epidermis and the epithelium






44. The removal of hydrogen or electrons from a compound or addition of oxygen; half of a redox (oxidation or reduction) process






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






46. The outermost surface of an organism






47. A tract of nerve fibers connecting the two cerebral hemispheres






48. The study of form and structure






49. The male gonads that produce sperm and male hormones
