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. All store energy within their chemical bonds.






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






3. Anabolism






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






5. Engages in both passive and active transport.






6. The phyla of round worms.






7. 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).






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






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






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






11. 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






12. The destruction of gametes - (sex cells such as sperm and eggs).






13. Is comprised of all the organisms that interact within a given ecosystem whether or not it is at carrying capacity.






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






15. Enzymes are usually __________ to certain reactions.






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






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






18. The phyla composed of segmented worms.






19. A hydrogen bond involves the ________________ and can be easily broken.






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






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






22. The individual we recognize as an adult fern.






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






24. Assumes that there are periods of stability during which little evolutionary change occurs - and that speciation can occur rapidly over a very short period of time.






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






26. In DNA Thymine pairs with...






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






28. An enzyme is unaffected by the reactions it catalyzes






29. Is when expression of genetic traits is determined by weather the trait is inherited from the mother or the father.






30. The sharp boundary of an ecosystem.






31. 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.






32. The trachea includes the windpipe or larynx in its upper portion - and the glottis - an opening that allows the gases to pass into the two branches known as the bronchi.






33. Produce adrenaline. This hormone is a well-known constrictor of blood vessels.






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






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






36. Mass extinctions promote diversification because _______________ - making conditions favorable for the establishment of new - diverse species.






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






38. 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.






39. Are formed when the plasma membrane of a cell encloses a molecule outside the membrane - then releases a membrane bound sack containing the desired molecule into the cytoplasm. This process allows the cell to absorb molecules that are larger in size






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






41. Controls balance and muscle coordination






42. What phylum are snakes in?






43. 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






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






45. Are cells involved in immunity and are produced in bone marrow as stem cells.






46. Transparency - polarity - high specific heat - and density (lower density when solid than when liquid.).






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






48. 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






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






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