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. The process whereby cells build molecules and store energy (in the form of covalent chemical bonds).






2. Is the organelle where cellular reproductive processes occur.






3. The destruction of gametes - (sex cells such as sperm and eggs).






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






5. Are cells involved in immunity and are produced in bone marrow as stem cells.






6. Covers and protects the leaf.






7. A type of innate behavior (instinct.) The FAP is a preprogrammed response to a particular stimulus (known as a releaser stimulus). FAP's include courtship behaviors and feeding of young. These are not learned behaviors - they are automatically perfor






8. Some patrol the blood for antigens - but are also equipped to destroy antigens. They may regulate immune responses as well.






9. Develops from the morula as a thin layer of cells surrounding an internal cavity.






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






11. The physical place where a particular organism lives. It must include all the factors that will support its life and reproduction.






12. 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






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






14. Is a coenzyme required in the synthesis of collagen.






15. Are produced when water passes through the cell membrane by osmosis from an area of higher concentration to an area of lower concentration - to equalize water concentration.






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






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






18. Is a phylum that contains sponges.






19. Contains optic lobes - controls sight.






20. Are more closely related to Homo Sapiens than to other apes - but Homo Sapiens did not evolve from chimpanzees.






21. An orienting response to light.






22. Veins in the leaf and are also distributed throughout the stem






23. Breaking down






24. In DNA Guanine pairs with...






25. Synthesis






26. A hydrogen bond involves the ________________ and can be easily broken.






27. The bronchi lead to the two lungs where they branch out in all directions into smaller tubules known as bronchioles.






28. Is the number of organisms that can be supported within a particular ecosystem.






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






30. May be ions or non-protein molecules - they are similar to cofactors - but differ in that they are tightly attached by covalent bonds to the enzyme - rather than being separate atoms or molecules.






31. Occurs when two populations are geographically isolated from each other. Over time this results in the production of two separate species.






32. Energy transformations that occur as chemicals are broken down or synthesized within the cell.






33. The individual we recognize as an adult fern.






34. Is comprised of all the organisms that interact within a given ecosystem whether or not it is at carrying capacity.






35. Is composed of a double layer (bilayer) of phospholipids with protein globules imbedded within the layers. The construction of the membrane allows it to aid the function of the cell by permitting entrance and exit of molecules as needed by the cell.






36. Is the major component of sand and is the most abundant element found in the lithosphere. It is not recycled.






37. Some energy is lost as heat and becomes unusable.






38. Is an abundant element found in protoplasm. Together with oxygen - hydrogen - and nitrogen - it composes over 90% of cellular structure.






39. The effect of a substrate concentration on the initial reaction rate in the presence of a limited amount of enzyme: _________________ as the concentration of substrate is increased until all the enzymes are used - then the reaction rate will level of






40. 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.






41. Stood upright before there was an increase in brain size.






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






43. Is a molecule that stores information for protein synthesis and genetic coding.






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. Absorb a photon of light and is found in the grana of the chloroplast.






46. Super-class of vertebrae including organisms with jaws.






47. Small - green - heart-shaped gametophyte plant form of a fern that can make its own food and absorb water and nutrients from the soil






48. The most recent and present era. It includes the radiation of flowering plants - the angiosperms.






49. Carbon - Hydrogen - Oxygen - and Nitrogen






50. Must be present for photosynthesis to occur - it is not used up in the process.
