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






2. Layer that will become the skin - some endocrine glands - and the nervous system.






3. Is found on the stem between nodes.






4. An enzyme is unaffected by the reactions it catalyzes






5. Contain organisms that are multicellular eukaryotes including vertebrates and invertebrates.






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






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






8. Disease causing






9. Where protein synthesis occurs. They float unattached in the cytoplasm. They contain RNA that is specific to their function in protein formation.






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






11. The lineage that led to the modern Homo Sapiens diverged from the lineage that led to the modern chimpanzee.






12. The sharp boundary of an ecosystem.






13. Has loosely packed cells that allow for gas and moisture exchange.






14. Ended with the extinction of the dinosaurs.






15. Chlorophyll pigments absorb photons of light - leaving the chlorophyll in a higher energy (excited) state - these then supply energy to reactions that produce ATP from ADP and Pi.






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






17. Process in which elements - chemical compounds - and other forms of matter are passed from one organism to another and from one part of the biosphere to another.






18. Is weaker than ionic - covalent - disulfide - or double bonds.






19. Controls sensory and motor responses - and controls memory - speech - and intelligence factors.






20. Covers and protects the leaf.






21. Becomes available for erosion as undersea sedimentary rocks are up-thrust by volcanic activity - erosion releases it from rocks into streams where it combines with oxygen to form phosphates in lakes that are then absorbed by plants - it is recycled t






22. Occurs when an individual from an adjacent population of the same species immigrates and breeds with a member of a previously locally isolated group - resulting in a change in the gene pool.






23. 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.






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






25. The total amount of genetic information available for a given species.






26. Contain one celled eukaryotes such as algae and protozoa.






27. Is a special protein that acts as a catalyst for organic reactions.






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






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






30. In order to become an established part of an island ecosystem there must be a populations large enough to ensure _________ - a food source - a suitable habitat - and a source of moisture.






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






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






33. Enzymes are usually __________ to certain reactions.






34. Controls balance and muscle coordination






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






36. 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.






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






38. Is the period when the cell is active in carrying on the function it was designed to perform within the organism. Cells spend much more time in interphase than in cell division.






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






40. Most chemical pollutants accidentally ingested by humans are __________ - mixed with broken down pigments in the bile - then bile is secreted into the small intestine - proceeds to the large intestine - and is expelled in the feces.






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






42. Is composed of an anterior and posterior lobe. The stalk of the lobe is connected to the hypothalamus. Antidiuretic Hormone (AH) is produced in the hypothalamus and stored in the posterior pituitary. Upon nervous stimulation from the hypothalamus - t






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






44. The vocal cords are found in the larynx.






45. 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).






46. Fossilized burrows from multicellular organisms begin to appear in the geological record approximately 700 million years ago during the Precambrian period. These multicellular animals had only soft parts and could not be fossilized.






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






48. The phyla of sponges.






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






50. Produce seeds without flowers. They include conifers (cone-bearers) and cycads.
