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. (of some plants or fungi) feeding on dead or decaying organic matter






2. Proposes that those individuals within a population that are most adapted to the environment are also the most likely individuals to produce viable offspring.






3. Secretes insulin to lower blood sugar and maintain equilibrium. A person eats three candy bars. Within minutes this endocrine gland affects blood-glucose homeostasis.






4. Is a phylum that contains sponges.






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






6. Is the outermost of the three main layers of an embryo.






7. The sharp boundary of an ecosystem.






8. 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).






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






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






11. An enzyme is unaffected by the reactions it catalyzes






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






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






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






15. Ended with the extinction of the dinosaurs.






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






17. Are easily converted to ATP - but the main energy products of the Krebs cycle liberate electrons then used in the electron transfer reactions.






18. An orienting response to light.






19. Carbon - nitrogen - phosphorous - and water. These are all recycled through biogeochemical processes.






20. Controls hunger and thirst






21. Assumes that there are periods of stability during which little evolutionary change occurs - and that speciation can occur rapidly over a very short period of time.






22. States that where random mating is occurring within a population that is in equilibrium with its environment - the gene frequencies and genotype ratios will remain constant from generation to generation. It is a mathematical formula that shows why re






23. Algae and Protozoa belong to the kingdom...






24. Is a compound fruit that forms from several ovaries of separate flowers that fuse together during ripening (strawberry - or pineapple).






25. Is very rare and is not absorbed by plant leaves. Phosphorous is nearly always found in solid form.






26. In both living and non-living environments.






27. Are formed when the plasma membrane of a cell encloses a molecule outside the membrane - then releases a membrane bound sack containing the desired molecule into the cytoplasm. This process allows the cell to absorb molecules that are larger in size






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






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






30. Is a kingdom that includes algae and protozoa.






31. Contains multicellular photosynthetic eukaryotic organisms including gymnosperms and angiosperms.






32. The cells of a developing embryo (at the gastrula stage) differentiate into layers - that will later develop into different tissues and organs - including the mesoderm - ectoderm - and endoderm.






33. 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.






34. An opportunistic life strategy strategy. Lichens invading a bare rock area after a volcanic eruption is an example.






35. 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






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






37. This is a carboxyl group and is the signature group found within organic acids.






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






39. Covers and protects the leaf.






40. Is a kind of plain characterized by a warm climate - grassland - and seasonally dry climate conditions.






41. The pituitary gland.






42. Is an ion that binds to an enzyme making it more able to catalyze a reaction.






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






44. Is the organelle where cellular reproductive processes occur.






45. Engages in both passive and active transport.






46. Are where the sugars synthesized by photosynthesis travel through to various parts of the plant.






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






48. Respiratory organs within insects






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






50. 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
