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






2. Plant growth stimulated by light (stem: + - towards light; root: - - away from light)






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






4. The junction or gap between the axon terminal of one neuron and the dendrites of another neuron






5. A simple sugar






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






7. A gland composed of two parts - anterior and posterior - each with its own secretions; called the "master gland" because its hormones stimulate secretions by other glands






8. An organelle in the cytoplasm that contains RNA; serves as the site of protein synthesis






9. The intake of food from the environment into the alimentary canal






10. The part of the body of an animal that is between the neck or head and the abdomen






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






12. The large intestine






13. The elimination of metabolic waster matter






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






15. A nitrogen base such as cytosine - thymine and uracil; when joined with sugar or phosphate - a component of nucleotides and nucleic acids






16. An antipathogenic substance (e.g. - penicillin)






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






18. Any chromosome that is not a sex chromosome






19. Usually referred to as ACTH and secreted by the anterior lobe of the pituitary gland; stimulates the adrenal cortex to produce its characteristic hormones






20. The physical appearance or makeup of an individual - as opposed to its genetic makeup






21. The portion of a DNA molecule that serves as a unit of heredity; found on the chromosome






22. A stomach enzyme that partially digests proteins






23. The tenth cranial nerve that innervates digestive organs - heart and other areas






24. The triploid tissue in some seeds that contains stored food and is formed by the union of one sperm nucleus with two nuclei of the female's gametophyte






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






26. A metabolic stage between mitoses in which genetic material is reproduced






27. The portion of seed plant embryo above the cotyledon






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






29. A five carbon sugar that has one oxygen atom less than ribose; a component of DNA






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






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






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






33. 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






34. The reproductive organ that produces sex cells






35. An association between an algae and a fungus that is symbiotic and mutualistic in nature






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

38. One or two or more types of genes - each representing a particular trait; many alleles exist for a specific gene locus






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






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






41. Any movement or growth of a living organism in response to the force of gravity






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






43. An excretory product of protein metabolism

45. One of a pair of kidney-shaped cells that surround a stomate and regulate the size of the stomate in a leaf






46. The passive - rhythmical expansion or dilation of the cavities of the heart (atria or ventricles) that allows these organs to fill with blood; preceded and followed by systole (contraction)






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