CLEP Biology

Subjects : clep, 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. Has loosely packed cells that allow for gas and moisture exchange.






2. Is a phylum that contains sponges.






3. The phyla composed of segmented worms.






4. Plants and animals obtain usable nitrogen






5. Produces the most ATP molecules - yielding 34 ATPs per glucose molecule.






6. The sharp boundary of an ecosystem.






7. Has extreme hot or cold temperatures - with very low precipitation - sandy or rocky terrain - sparse vegetation (mainly succulents) - small animals - rodents - and reptiles.






8. Is a compound fruit that develops from many ovaries of a single flower fusing together (raspberry).






9. Biotic (living) factors such as population and food source - and abiotic (non-living) factors such as weather - temperature - soil features - sunlight).






10. Is the process that releases energy for use by the cell.






11. Internally generated patterns of body functions - including hormonal signals - sleep - blood pressure - and temperature regulation - which have approximately a 24-hour cycle and occur even in the absence of normal cues about whether it is day or nigh






12. Is a behavior that is learned during a critical point (often very early) in an individual's life. Imprinting enables the young the recognize members of their own species.






13. Allows for the genetic code to be preserved in future generations of cells.






14. Is a packet of digestive enzymes that destroy cellular wastes.






15. Are organic cofactors or coenzymes that are required by some enzymatic reactions.






16. Fruits that develop from a single ripened ovary (apple - olive - acorn - cucumber).






17. In DNA Guanine pairs with...






18. The number of organisms in a given community - can be above or below the carrying capacity.






19. Are the organelles where cellular respiration occurs.






20. Channels is cell membranes that carry water between cells.






21. An orienting response to light.






22. Digestive enzymes - hydrochloric acid - and gastric juices which aid in digestion. The mucous secreted by the stomach protects the stomach lining from the acids and juices.






23. Process of breaking down complex materials (foods) to form simpler substances and release energy.






24. Are the monomers that form nucleic acids - containing a sugar - phosphate group - and a nitrogenous base.






25. Sex-linked recessive disorder carried on the x chromosome defined by the absence of one or more proteins required for blood clotting






26. Is found in the root cap and is responsible for quick growth in the roots.






27. Consists of undifferentiated cells capable of quick growth and specialization. It is responsible for elongation of the stem.






28. The solid mass of cells resulting from the cleavage of the ovum before the formation of a blastula.






29. Is found on the stem between nodes.






30. Has an equal (50%) chance of being passed from a carrier mother to a son or a daughter.






31. The pharynx is between the nasal passage and the trachea. Air passes into the body via the nasal passage - then passes through the pharynx and on to the trachea.






32. The role played by an organism in its food chain.






33. Some enzymes contain a __________ component that is essential to their functions.






34. The size of a cell is limited by the ratio of its surface area to volume.






35. Is a social behavior of an organism that is beneficial to the group at the individual's expense.






36. Include: Vascular tissue - including both xylem and phloem - and sieve plates existing between cells of the stem.






37. Attaches to an enzyme and blocks the enzyme reaction rather than enhancing it - like a prosthetic group would.






38. Plants that produce flowers as reproductive organs. They have two divisions - monocots and dicots.






39. A sex-linked recessive disorder carried on the x chromosome in which an individual cannot perceive certain colors.






40. Contains organisms that are multicellular eukaryotes including molds and mushrooms.






41. The systematic search for individuals with a specific genotype in a delineated population.






42. Can be accounted for by the theory of punctuated equilibrium. The fossil record shows periods of stability with regard to appearance and disappearance of species as well as periods of sudden change.






43. Is a kingdom that includes algae and protozoa.






44. Is a disease caused by lack of vitamin C in which the body is unable to build enough collagen (a major component of connective tissue).






45. All store energy within their chemical bonds.






46. Studied the relationships between traits expressed in parents and offspring and the genes that caused the traits to be expressed.






47. Are tubes constructed of a geometrical arrangement of microtubules in a pinwheel shape. Their function includes the formation of new microtubules - but is primarily to form the structural skeleton around which cells split during mitosis and meiosis.






48. Super-class of vertebrae including organisms with no jaws.






49. Produce antibodies into the bloodstream that find and attach themselves to foreign antigens (toxins - bacteria).






50. Includes all living and nonliving components of the Earth to support living things.
