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






2. The female gonad in animals; the base of the pistil in plants






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






4. 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)






5. A microscopic opening located in the epidermis of a leaf and formed by a pair of guard cells






6. A flesh-eating animal; a holotrophic animal that subsists on other animals or parts of animals






7. The part of the hindbrain located in the brain stem






8. The microspore of a seed plant






9. The living matter of a cell - located between the cell membrane and the nucleus






10. A period in the development of animals between the embryo and adult stages; starts at hatching and ends in metamorphasis






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






12. Any chromosome that is not a sex chromosome






13. A network or mesh of fibrils - fibers or filaments






14. Organism that consumes food from outside itself instead of producing it






15. The science of classification of living things






16. An excretory product of protein metabolism






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






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






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






20. A large molecule that is composed of many similar molecule units






21. A stomach enzyme that partially digests proteins






22. A blood clot that is formed within a blood vessel






23. A type of anaerobic respiration found in fungi - bacteria and human muscle cells






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






25. A nuclear protein of chromosomes that stains readily






26. A membrane that envelopes the nucleus and separates it from the cytoplasm; present in eukaryotes






27. The central tissue of a stem - used for food storage






28. The area of medulla that regulates the rate of breathing






29. 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






30. 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

32. A fluid-filled sensory apparatus that aids balance and hearing






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






34. 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)






35. The recycling of carbon from decaying organisms for use in future generations






36. The inner portion of the cytoplasm of a cell or the portion that surrounds the nucleus






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






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






39. The final stages of protein synthesis in which the genetic code of nucleotide sequences is translated into a sequences of amino acids






40. A foreign protein that stimulates the production of antibodies when introduced into the body of an organism






41. Structures in the testes that produce sperm and semen






42. A mutation involving the addition or loss of nucleotides






43. All the members of a given species inhabiting a certain locale

46. A nitrogen base that is present in nucleotides and nucleic acids; it is paired with guanine






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






48. Describes structures that have similar function but different evolutionary origins; e.g. - a bird's wing and a moth's wing
