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. Technology that allows for manipulation of genetic material






2. Nonliving - as in the physical environment






3. The process of forming the sperm cells from primary spermatocytes






4. A flowering plant with simple dry fruit - characterized by nodes on their roots that contain nitrogen-fixing bacteria






5. A sugar composed of two combined monosaccharides






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






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






8. A thyroid deficiency that results in stunted growth and feeblemindedness






9. The male gonads that produce sperm and male hormones






10. The innermost embryonic germ layer that gives rise to the lining of the alimentary canal and to the digestive and respiratory organs






11. The portion of the embryonic seed plant below the point of attachment of the coytledon; form the root






12. Changes in genes that are inherited






13. An organ centrally involved in the human digestive system






14. A dense fluid within the chloroplast in which CO2 is converted into sugars in photosynthesis






15. In taxonomy - a classification between species and family






16. An antigen in blood; can cause erythroblastosis fetalis when the mother is Rh- and the fetus is Rh+






17. Describes organisms that are cooperative in action - such as hormones or other growth factors that reinforce each other's activity






18. A hoofed animal






19. An accumulation of axons within the CNS that is white because it is fatty - myelin sheath






20. Pertaining to the head






21. The haploid - sexual stage in the life cycle of plants






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






23. The most anterior portion of the small intestine of vertebrates - adjacent to the stomach; the continuation of the stomach into which the bile duct and pancreatic duct empty






24. A group of life-maintaining processes that includes nutrition - respiration (the production of usable energy) and the synthesis and degradation of biochemical substances






25. The sac in the ovary in which the egg develops






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






27. A cell in the retina that is sensitive to colors and is responsible for color vision






28. The genetic makeup of an organism without regard to physical appearance






29. The phylum of sponges






30. 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






31. The functional role and position of an organism in an ecosystem; embodies every aspect of the organism's existence






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






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






34. A typical coelenterate individual with a hollow tubular body whose outer ectoderm is separated from its inner ectoderm by mesoglea






35. A mitotic or meiotic stage in which the chromosomes become visible and during which the spindle fibers form; synapsis takes place during the first meiotic prophase






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






37. A network - particularly of nerve or blood vessels

39. A sensory hair structure in the utriculus and the sacculus of the inner ear; orients the head with respect to gravity






40. Living or active in the absence of free oxygen; pertaining to respiration that is independent of oxygen






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






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

48. The creation of certain strains of specific traits through control of breeding






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






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