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. An excretory product of protein metabolism






2. A response by an organism to the duration and timing of light and dark conditions






3. Nonfunctional haploid cells created during meiosis in females; they have very little cytoplasm-most has gone into the functional egg cell






4. Membranous organelles involved in the storage and modification of secretory products






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






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






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






8. Cytoplasmic organelles that serve as sites of respiration; a rod-shaped body in the cytoplasm known to be the center of cellular respiration






9. An organism that possesses both the male and the female reproductive organs






10. Pertaining to a subdivision of the autonomic nervous system






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






12. A vacuole in the cytoplasm in which digestion takes place (in protozoans)






13. A form of asexual reproduction in which the egg develops in the absence of sperm






14. Hormone active in osmoregulation; a mineral corticoid produced by the adrenal cortex; stimulates reabsorption of Na+ and secretion of K+






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






16. Semen






17. The separation of some members of a population from the rest of their species; prevents interbreeding and may lead to the development of a new species






18. A process of photosynthesis in which water is split into H+ and OH-; the hydrogen ion is then joined to NADP






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






20. An offspring that is heterozygous for one or more gene pairs






21. The primary germ layer - developed from the lip of the blastopore - that gives rise to the skeleton - the circulatory system and many organs and tissues between the epidermis and the epithelium






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






23. In plants - an area of undifferentiated tissue covered by embryonic leaves






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






25. 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)






26. A blood vessel that carries blood away from the heart






27. The place of attachment of the mitotic fiber to the chromosome

29. A carbohydrate that is composed of many monosaccharide units joined together






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






31. Multicellular organism






32. 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






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






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






35. Technology that allows for manipulation of genetic material

37. The enzyme that acts upon lactose






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

43. The outermost - extra-embryonic membrane of reptiles and birds






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






45. A disease-causing organism






46. A process by which the vesicle in the cell fuses with the cell membrane and releases its contents to the outside






47. A structure of the eye that focuses images on the retina by changing its convexity
