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. A starch form in animals; glucose is converted to this in the liver






2. A habitat zone - such as desert - grassland or tundra






3. A flesh-eating animal; a holotrophic animal that subsists on other animals or parts of animals






4. The thin - bent part of the renal tubule that is the site of the counter-current flow and the sodium gradient






5. An excretory product of protein metabolism






6. The process by which environmental patterns or objects presented to a developing organism during a "critical period" of its growth is accepted as a permanent element of its behavior






7. The conversion of digested foods and other materials into forms usable by the body (i.e. - the conversion of amino acids into proteins)






8. An association between an algae and a fungus that is symbiotic and mutualistic in nature






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






10. A hydrogen carrier containing iron that functions in many cellular processes - including respiration






11. The place of attachment of the mitotic fiber to the chromosome






12. Part of the nephron in the kidney; involved in excretion


13. A structure found between the cerebral hemispheres of vertebrates; secretes melatonin






14. A stage of mitosis; chromosomes line up at the equator of the cell






15. A large class of arthropods - including crabs and lobsters






16. The system of naming an organism by its genus and species name






17. A nitrogenous base such as adenine or guanine; when joined with sugar or phosphate - a component of nucleotides and nucleic acids






18. A type of virus that can destroy bacteria by infecting - parasitizing and eventually killing them






19. The largest artery; carries blood from the left ventricle






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






21. A network or mesh of fibrils - fibers or filaments






22. Outgrowths of a root's epidermal cells that allow for greater surface area for absorption of nutrients and water






23. A dark-staining small body within the nucleus; composed of RNA






24. Involuntary muscle






25. The part of the neuron that transmits impulses to the cell body






26. A cell that divides to form the polar body and the secondary oocyte






27. An undifferentiated - growing region of a plant that is constantly undergoing cell division and differentiation






28. A structure formed by the wall of the uterus and the chorion of the embryo; serves as the area in which the embryo obtains nutrition from the parent






29. Functional urinary tubules responsible for excretion in the kidney of vertebrates






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






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






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






33. The portion of a DNA molecule that serves as a unit of heredity; found on the chromosome






34. A kind of white blood cell in vertebrates that is characterized by a rounded nucleus; involved in the immune response






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






36. Describes arthropods and other animals whose skeletal or supporting structures are outside the skin
