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. xylem that is no longer being used






2. The state in which two genetic traits are fully expressed and neither dominates






3. A group of populations that can interbreed






4. A process by which the cell membrane is invaginated to form a vesicle which contains extracellular medium






5. A gland composed of two parts - anterior and posterior - each with its own secretions; called the "master gland" because its hormones stimulate secretions by other glands






6. A portion of the CNS consisting of cytons (cell bodies) - their dendrites and synaptic connections






7. The reproductive organ that produces sex cells






8. A plant growth hormone






9. Technology that allows for manipulation of genetic material






10. A fat-digesting hormone






11. The individual differences of form among the members of a species






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






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






14. The transfer of pollen to the micropyle or to a receptive surface that is associated with an ovule (such as stigma)






15. 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)






16. A marine biome; a region on the continental shelf that contains an ocean area with depths of up to 600 ft






17. A protein compound containing iron that is found in red blood cells






18. The ability of an organism to contribute its alleles and therefore is phenotypic traits to future generations






19. Usually referred to as ACTH and secreted by the anterior lobe of the pituitary gland; stimulates the adrenal cortex to produce its characteristic hormones






20. The recycling of nitrogen from decaying organism for use in future generations






21. The cellular layer that covers external and internal surfaces






22. The description of a plant life cycle that consists of a diploid - asexual - sporophyte generation and a haploid - sexual - gametrophyte generation

26. A cell that divides to form two secondary spermatocytes

29. A female sex hormone secreted by the follicle






30. Living or active in the absence of free oxygen; pertaining to respiration that is independent of oxygen






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






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






33. Vascular tissue of the plant that aids in support and carries water
