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 endocrine gland located in the neck that produces thyroxin






2. A flexible - supportive rod running longitudinally through the dorsum ventral to the nerve cord; found in lower chordates and in the embryos of vertebrates






3. The part of the nervous system that regulates the involuntary muscles - such as the walls of the alimentary canal; includes the parasympathetic and sympathetic nervous systems






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






5. The study of organisms in relation to their environment






6. An emulsifying agent secreted by the liver






7. A metabolic stage between mitoses in which genetic material is reproduced






8. A pouched mammal - such as the kangaroo or opossum






9. 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






10. A female sex hormone secreted by the follicle






11. A terrestrial habitat zone that is characterized by large tracts of coniferous forests - long and cold winters - and short summers






12. A behavioral or biological change that enables an organism to adjust to its environment






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






14. Pertaining to a subdivision of the autonomic nervous system






15. One of the primary tissues of the embryo






16. In plants - the tissue between the epidermis and the vascular cylinder in the roots and stems of plants; in animals - the outer tissue of some organs






17. Describes structures that have similar function but different evolutionary origins; e.g. - a bird's wing and a moth's wing






18. One of many tubules that absorb tissue fluid and return it to the bloodstream via the lymphatic system






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






20. The organelle that provides mechanical support and carries out motility functions for the cell






21. The inner part of the adrenal gland that secretes adrenalin






22. A mucus-secreting membrane






23. 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






24. The phylum to which segmented worms belong






25. Nonfunctional haploid cells created during meiosis in females; they have very little cytoplasm-most has gone into the functional egg cell






26. A reproductive cell






27. The largest portion of the human brain; it is believed to be the center of intelligence - conscious thought and sensation

29. The enzyme released from the blood platelets in vertebrates during clotting






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

32. A plant that has a single cotyledon or seed-leaf






33. The enzyme that acts upon lactose






34. The intake of fluid droplets into a cell

36. A marine arthropod - now extinct - that lived during the Paleozoic era
