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. Globular proteins produced by tissues that destroy or inactivate antigens






2. The removal of hydrogen or electrons from a compound or addition of oxygen; half of a redox (oxidation or reduction) process






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






4. The pairing of homologous chromosomes during meiosis






5. An organ that is not functional in an organism - but was functional at some period in its evolution






6. Describes an individual that has the same gene for the same trait on each homologous chromosome






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






8. An organism that requires oxygen for respiration and can live only in the presence of oxygen






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






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






11. An animal phylum in which all members have a notochord - dorsal nerve cord and pharyngeal gill slits at some embryonic stage; includes the Cephalochordata and the Vertebrates






12. Changes in genes that are inherited






13. The vascular tissue of a plant that transports organic materials (photosynthetic products) from the leaves to other parts of the plant






14. A stage of embryonic development in which the embryo consists of a hollow ball of cells






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






16. A fatty sheath surrounding the axon of a neuron that aids in stimulus transmission; it is secreted by the Schwann cells






17. A decimal fraction that represents the presence of an allele for all members of a population that have a particular gene locus






18. Movement of amoeba






19. The cavity in the mammalian ovary in which the egg ripens






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






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






22. A "seed leaf"; responsible for food digestion and storage in plant embryo






23. A hormone that regulates water reabsorption






24. The evaporation of water from leaves or other exposed surfaces of plants






25. An antigen in blood; can cause erythroblastosis fetalis when the mother is Rh- and the fetus is Rh+

31. An enzyme that acts upon sucrose






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