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 chamber in the alimentary canal of certain vertebrates located below the large intestine - into which the ureter and reproductive organs empty (as in frogs)






2. The exchange of parts of homologous chromosomes during meiosis






3. A stalklike or elongated body part - usually pointed at one end






4. Plant growth stimulated by light (stem: + - towards light; root: - - away from light)






5. The study of the evolutionary descent and interrelations of groups of organisms






6. The genetic makeup of an organism without regard to physical appearance






7. A cell in the retina that is sensitive to weak light






8. A duct that carries urine from the kidneys to the bladder






9. One or two or more types of genes - each representing a particular trait; many alleles exist for a specific gene locus






10. One of a group of compounds that is identical in a atomic composition - but different in structure and arrangement






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






12. The reproductive organ that produces sex cells






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

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






19. An organelle that regulates cell functions and contains the genetic material of the cell

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






22. The posterior part of the brain that controls the rate of breathing and other autonomic functions

29. A fat or oil






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