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 and animals obtain usable nitrogen






2. Contains many genes and is a structure comprised of linear DNA and associated proteins.






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

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






10. Synthesis

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






13. 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






14. Are easily converted to ATP - but the main energy products of the Krebs cycle liberate electrons then used in the electron transfer reactions.






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






16. Attaches to an enzyme and blocks the enzyme reaction rather than enhancing it - like a prosthetic group would.






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






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






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






20. 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.






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






22. Develops from the morula as a thin layer of cells surrounding an internal cavity.






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






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






25. 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.






26. Subsets below the kingdom level






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






28. Is a kingdom that includes algae and protozoa.






29. Enzymes are usually __________ to certain reactions.






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






31. Protein synthesis






32. What phylum are snakes in?






33. 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






34. Must be present for photosynthesis to occur - it is not used up in the process.






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






36. Layer that will become the skin - some endocrine glands - and the nervous system.






37. 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.






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






39. In DNA Guanine pairs with...






40. Layer that will become the gut lining as well as some accessory structures.






41. 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.






42. 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).






43. Covers and protects the leaf.






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