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.

3. The portion of alimentary canal in which some protein digestion occurs






4. 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






5. An accumulation of axons within the CNS that is white because it is fatty - myelin sheath






6. An embryonic structure that gives rise to the central nervous system






7. The central tissue of a stem - used for food storage






8. The sensory branch of each spinal nerve






9. Movement of amoeba






10. The study of all living processes - activities and functions






11. The part of the flower that bears the female gametophyte






12. Waves of contraction and relaxation passing along a tubular structure - such as the digestive tube






13. An abbreviation of nicotinamide-adenine-dinucleotide - also called DPN; a respiratory oxidation-reduction molecule






14. The breeding of an organism with a homozygous recessive in order to determine whether an organism is homozygous dominant or heterozygous dominant for a given trait






15. Blood protein that is transformed to fibrin upon clotting






16. Describes organisms that are cooperative in action - such as hormones or other growth factors that reinforce each other's activity






17. The liquid part of blood






18. Cycle in photosynthesis that reduces fixed carbon to carbohydrates through the addition of electrons ("dark cycle")






19. Related to the sense of smell






20. A cell resulting from the fusion of gametes






21. A process of photosynthesis in which water is split into H+ and OH-; the hydrogen ion is then joined to NADP

23. A plant-eating animal






24. Pertaining to a type of gland that releases its secretion through a duct

33. The cavity between the lungs and the wall of the chest






34. A purine (nitrogenous base) component of nucleotides and nucleic acids; links with cytosine in DNA






35. The primary germ layer - developed from the lip of the blastopore - that gives rise to the skeleton - the circulatory system and many organs and tissues between the epidermis and the epithelium






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

38. The sensory organ of the inner ear of mammals; it is coiled and contains the organ of corti






39. A duct through which the urine passes from the bladder to the outside






40. A constituent of the plasma of the blood of vertebrates; it is converted to thrombin by thrombokinase in the presence of calcium ions - thus contributing to the clotting of blood
