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. Occurs when different traits are inherited together more often than they would have been by chance along; it is assumed that these traits are linked on the same chromosome






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






3. An ion with a positive charge - or an ion that migrates towards the cathode (negative electrode) in an electric field






4. The movement of particles from one place to another as a result of their random motion






5. Any physical feature that prevents the ecological niches of different organisms from overlapping






6. A four-letter code made up of the DNA nitrogen bases A - T - G and C; each chromosome is made up of thousands of these bases






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






8. The conversion of digested foods and other materials into forms usable by the body (i.e. - the conversion of amino acids into proteins)






9. Describes a fluid that has the same osmotic pressure as a fluid it is compared to






10. Bacteria that are rod shaped






11. Partially digested food in the stomach






12. An association of homologous chromosomes during the first meiotic division






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






14. Three membranes that envelop the brain and spinal cord (pia mater - dura mater and arachnoid)






15. 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






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

18. The anaerobic respiration of carbohydrates






19. Requiring free oxygen from the atmosphere for normal activity and respiration






20. An organism that is heterozygous for two different traits






21. Describes an organism that lives symbiotically with a host; this host neither benefits nor suffers from the association






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






23. The transformation of an immature animal into an adult; a change in the form of an organ or structure






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






25. The biome located between the polar region and the tiaga






26. The system of naming an organism by its genus and species name






27. A process of formation of ova






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






29. The association of physical - visceral response with an environmental stimulus with which it is not naturally associated; a learned response






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






31. A sugar composed of two combined monosaccharides






32. Any chromosome that is not a sex chromosome






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






34. Occurs when a segment of genetic material on a chromosome becomes reversed






35. An opening in the eye whose size is regulated by the iris






36. A dominant allele suppresses the expression of the other member of an allele pair when both members are present






37. The breeding of an organism with a homozygous recessive in order to determine whether an organism is homozygous dominant or heterozygous dominant for a given trait






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

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






45. The ability of certain animals to regrow missing body parts






46. A type of virus that can destroy bacteria by infecting - parasitizing and eventually killing them






47. An anterior pituitary hormone that stimulates the follicles in females and the function of the seminiferous tubules in males
