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 female gamete; it is nonmotile - large in comparison to male gametes - and stores nutrients






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






3. The production of daughter cells by means other than the sexual union of gametes (as in budding and binary fission)






4. The elimination of metabolic waster matter






5. The process by which environmental patterns or objects presented to a developing organism during a "critical period" of its growth is accepted as a permanent element of its behavior






6. Deoxyribonucleic acid; found in cell nucleus - its basic unit is the nucleotide; contains coded genetic information; can replicate on the basis of heredity






7. The cellular layer that covers external and internal surfaces






8. A tube connecting the ovaries and the uterus






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






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






11. Functional urinary tubules responsible for excretion in the kidney of vertebrates






12. Tissue formed by the differentiation of cambium that causes a growth in width of a plant system






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






14. An organism that is heterozygous for two different traits






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






16. Living - as in living organisms in the environment






17. Changes in genes that are inherited






18. Describes cells that have a double set of chromosomes in homologous pairs (2n)






19. The outermost embryonic germ layer that gives rise to the epidermis and the nervous system






20. An organic catalyst and protein






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






22. A process of asexual reproduction in which the offspring develop from an outgrowth of the plant or animal






23. 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)






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






25. A process by which the cytoplasm and the organelles of the cell divide; the final stage of mitosis






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






27. The contraction of the atria or ventricles of the heart






28. The study of organisms in relation to their environment






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






30. Cytoplasmic bodies within a plant cell that are often pigmented






31. Compounds in bile that aid in emulsification






32. A microscopic - whiplike filament that serves as a locomotor structure in flagellate cells






33. There are two kinds of sex chromosomes - X and Y; XX signifies a female and XY signifies a male






34. A category of taxonomic classification that is ranked above class and under kingdoms






35. A resistance to disease developed through the immune system






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






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






38. An invertebrate animal phylum in which animals possess a single alimentary opening and tentacles with stinging cells






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






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






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






42. The exchange of parts of homologous chromosomes during meiosis






43. Occurs when certain traits are determined by genes on sex chromosomes






44. The junction or gap between the axon terminal of one neuron and the dendrites of another neuron






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






46. Multicellular organism






47. A space in the cytoplasm of a cell that contains fluid






48. A digestive enzyme of the saliva that turns starch into maltose (salivary amylase)






49. An abbreviation of ribonucleic acid - a nucleic acid in which the sugar is ribose; a product of DNA transcription that serves to control certain cell activities






50. Daily cycles of behavior
