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






2. An organic molecule consisting of joined phosphate - 5-carbon sugar (deoxyribose or ribose) - and a purine or a pyrimidine (adenine - guanine - uracil - thymine or cytosine)






3. A network - particularly of nerve or blood vessels






4. Laws of classical genetics established through Mendel's experiments with peas






5. One of the primary tissues of the embryo






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






7. An abbreviation of nicotinamide-adenine-dinucleotide-phosphate - also called TPN; an organic compound that serves as an oxidation-reduction molecule






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






9. An organic nutrient required by organisms in small amounts to aid in proper metabolic processes






10. The phylum to which jointed-legged invertebrates belong - including insects - arachnids and crustaceans






11. A chemical messenger that is secreted by one part of the body and carried by the blood to affect another part of the body - usually a muscle or gland






12. Adrenaline






13. One of many tubules that absorb tissue fluid and return it to the bloodstream via the lymphatic system






14. Encompasses the brain and the spinal cord






15. Living - as in living organisms in the environment






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






17. The pigment in rod cells that causes light sensitivity






18. An organ that stores bile






19. A symbiotic relationship from which both organisms involved derive some benefit






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






21. The second filial generation; offspring resulting from the crossing of individuals of the F1 generation






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






23. The inner part of the adrenal gland that secretes adrenalin






24. The phylum to which segmented worms belong






25. Pertaining to the head






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






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

29. A 12-carbon sugar that is formed by the union of two glucose units (a disaccharide)






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






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






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






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