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






2. Disease causing






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






4. Niche






5. Plants and animals obtain usable nitrogen






6. Contains optic lobes - controls sight.






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






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






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






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






11. Between the endoderm and ectoderm - layer that will eventually form the muscles - and organs of the skeletal - circulatory - respiratory - reproductive - and excretory systems.






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






13. High temperatures






14. In both living and non-living environments.






15. Is disorganized - unravelled - DNA with histones attached.






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






17. Are surrounded by capillaries that allow for carbon dioxide to diffuse into the lungs and oxygen to diffuse out.






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






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






20. 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.






21. 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






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






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






24. Bacteria break ammonia into nitrites - then into nitrates that are usable by plants; volcanic activity produces ammonia and nitrates that enter the soil and can be absorbed by plants; lightning reacts with atmospheric nitrogen to form nitrates that a






25. 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






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






27. Covalent bonds






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






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






30. An enzyme is unaffected by the reactions it catalyzes






31. Is the earliest period of the Paleozoic era. Began with the Cambrian explosion - this explosion of life resulted in the representatives of most of the modern phyla being present.






32. 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.






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






34. 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.






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






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






37. Breaking down






38. The vocal cords are found in the larynx.






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






40. 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.






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






42. Synthesis






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






44. Is the control of protein synthesis. Genetic traits are expressed and specialization of cells occur as a result of the combination of proteins produced by the DNA of a cell.






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






46. Decomposition of living matter for consumption.






47. 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






48. Is the organelle where cellular reproductive processes occur.






49. Covers and protects the leaf.






50. Refers to the birthrate of a population.
