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. A remnant of follicle after ovulation that secretes the hormone progesterone






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






4. The hormone secreted by the corpus luteum of vertebrates and the placenta of mammals; its function is to maintain the endometrium






5. The pairing of homologous chromosomes during meiosis






6. Plant tissue consisting of large thin-walled cells for storage






7. A specialized structure that leads to the digestive tract of a developing organism and provides it with food during early development






8. The intake of food from the environment into the alimentary canal






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






10. 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






11. Agent that induces mutations; typically carcinogenic






12. Refers to protective covering






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






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






15. The diffusion of water through a semipermeable membrane - from an area of greater concentration to an area of lesser concentration






16. An underground stem






17. The class of free-living flatworms






18. An antipathogenic substance (e.g. - penicillin)






19. Describes an individual that has the same gene for the same trait on each homologous chromosome






20. The vascular tissue of a plant that transports organic materials (photosynthetic products) from the leaves to other parts of the plant






21. Globular proteins produced by tissues that destroy or inactivate antigens






22. A nitrogen base that is present in nucleotides and nucleic acids; it is paired with guanine






23. An enzyme from the pancreas that digests proteins in the small intestine






24. A short - stubby rod consisting of chromatin that is found in the nucleus of the cells; contains the genetic or hereditary component of cells (in the form of genes)






25. A group of populations that can interbreed






26. A hormone produced by the Islets of Langerhans in the pancreas






27. 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






28. An enlargement of the thyroid gland due to lack of iodine






29. The recycling of carbon from decaying organisms for use in future generations






30. The removal of an amino group from an organism - particularly from an amino acid






31. A neuron that picks up impulses from receptors and transmits them to the spinal cord






32. The tenth cranial nerve that innervates digestive organs - heart and other areas

34. A form of asexual reproduction in which the egg develops in the absence of sperm






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






36. The triploid tissue in some seeds that contains stored food and is formed by the union of one sperm nucleus with two nuclei of the female's gametophyte
