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






2. Is made of stacked cells connected by sieve plates that allow nutrients to pass from cell to cell. They transport food made in the leaves (by photosynthesis) to the rest of the plant).






3. The preservation of the integrity of genetic information from one generation to another.






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






5. The large brain and upright posture of Homo Sapiens...






6. The class composed of birds.






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






8. Inorganic phosphate






9. Occurs when an individual learns not to respond to a particular stimulus - for instance when a stimulus is repeated many times without consequence.






10. Is a phylum that contains jellyfish - hydra - etc.






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






12. Plants and animals obtain usable nitrogen






13. Niche






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






15. Nonvascular plants such as mosses which lack tissue for conducting food or water.






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






17. Is an accidental change of the DNA sequence of the gene that can result in creating a change of trait that is not found in the parent.






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






19. Ended with the extinction of the dinosaurs.






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






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






22. An orienting response to light.






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






24. 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.






25. Contains the chromosomes and is the site of reproduction through mitosis and meiosis.






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






27. Disease causing






28. Enzymes are usually __________ to certain reactions.






29. 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.






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






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






32. Engages in both passive and active transport.






33. In DNA Thymine pairs with...






34. Breaking down






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






36. 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.






37. The part of the earth that contains all living things - including the atmosphere (air) - the lithosphere (earth) - and the hydrosphere (water).






38. When stems bend toward the light it is due to _____________ the hormone auxin - in response to light - migrates from the light to the dark side of the shoot tip. The cells on the dark side now contain more auxin - which causes the cells on that side






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






40. 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






41. The transfer of electrons.






42. A reaction that adds water to another compound. (2 hydrogens - 1 oxygen).






43. Is a phylum that contains sponges.






44. A suffix meaning 'to break apart.' O || ||






45. In DNA Guanine pairs with...






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






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






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






49. 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.






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