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






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






3. 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.






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






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






6. 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






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






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






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






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






11. Covalent bonds






12. Covers and protects the leaf.






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






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






15. 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.






16. Controls balance and muscle coordination






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






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






19. 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.






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

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






22. 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






23. An orienting response to light.






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






25. Is more like branching out of a tree with dead ends and new branches appearing simultaneously than like steps on a ladder.






26. Is an abundant element found in protoplasm. Together with oxygen - hydrogen - and nitrogen - it composes over 90% of cellular structure.






27. Some enzymes contain a __________ component that is essential to their functions.






28. 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.






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






30. The phyla of round worms.






31. Transfers water and does not require sieve plates to allow nutrients through.






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






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






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






35. 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






36. When the water concentration inside and outside the cell is equal - It is said to be in an...






37. What phylum are snakes in?






38. Is the outermost layer of cells of the stem.






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






40. Controls hunger and thirst






41. 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.






42. Sex-linked recessive disorder carried on the x chromosome defined by the absence of one or more proteins required for blood clotting






43. Respiratory organs within insects






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






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






46. Is a kingdom that includes algae and protozoa.






47. 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






48. The process whereby cells build molecules and store energy (in the form of covalent chemical bonds).






49. 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).






50. 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).
