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 number of organisms in a given community - can be above or below the carrying capacity.






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






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






4. 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.






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






6. The pharynx is between the nasal passage and the trachea. Air passes into the body via the nasal passage - then passes through the pharynx and on to the trachea.






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






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






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






10. 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.






11. Is found on the stem between nodes.






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






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






14. In both living and non-living environments.






15. Are the organelles where cellular respiration occurs.






16. Refers to the birthrate of a population.






17. Inorganic phosphate






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






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






20. 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.






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






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






23. Are membrane-bound organelles that contain digestive enzymes that digest dead or unused material within the cell or materials absorbed by the cell for use.






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






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






26. High temperatures






27. The phyla of sponges.






28. 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






29. It secretes saliva which enters the digestive tract and aids the digestive process.






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






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






32. Covalent bonds






33. 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).






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






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






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






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






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






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






41. Mitochondria - they constitute the center of cellular respiration.

42. Is the sugar that lactase acts upon.






43. An orienting response to light.






44. Decomposition of living matter for consumption.






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






46. 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






47. Has extreme cold temperatures - low precipitation - modified grassland - perma-frost - a short growing season and some plants and animals.






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






49. In DNA Thymine pairs with...






50. Is secreted by the adrenal cortex to promote sodium reabsorption in the kidney.
