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 animal with a constant body temperature






2. Requiring free oxygen from the atmosphere for normal activity and respiration






3. The stage in mitosis that is characterized by the migration of chromatids to opposite ends of the cell; the stage in meiosis during which homologus pairs migrate (Anaphase I) - and the stage in meiosis during which chromatids migrate to different end






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






5. A ring-shaped muscle that is capable of closing a tubular opening by constriction






6. A space in the body






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






8. A thyroid deficiency that results in stunted growth and feeblemindedness






9. The transformation of an immature animal into an adult; a change in the form of an organ or structure






10. Cells which in the female are located between the ovarian follicles and in the male are located between the seminiferous tubules of the testes






11. An organism that utilizes the energy of inorganic materials such as water and carbon dioxide or the sun to manufacture organic materials






12. A change from a diploid nucleus to a haploid nucleus - as in meiosis






13. A cell that divides to form two secondary spermatocytes






14. An anterior pituitary hormone that stimulates the follicles in females and the function of the seminiferous tubules in males






15. The external opening of the trachea in insects






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






17. The study of form and structure
