CLEP Biology

Subjects : clep, science, biology
  • 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. Layer that will become the gut lining as well as some accessory structures.

2. The sharp boundary of an ecosystem.

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

4. Engages in both passive and active transport.

5. 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.

6. Biotic (living) factors such as population and food source - and abiotic (non-living) factors such as weather - temperature - soil features - sunlight).

7. An opportunistic life strategy strategy. Lichens invading a bare rock area after a volcanic eruption is an example.

8. Protein synthesis

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

10. Studied the relationships between traits expressed in parents and offspring and the genes that caused the traits to be expressed.

11. The phyla composed of segmented worms.

12. 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.

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

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

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

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

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

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

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

20. Subsets below the kingdom level

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

22. Controls olfactory lobes (smell)

23. Breaking down

24. Plants and animals obtain usable nitrogen

25. 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

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

27. In both living and non-living environments.

28. 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

29. May be ions or non-protein molecules - they are similar to cofactors - but differ in that they are tightly attached by covalent bonds to the enzyme - rather than being separate atoms or molecules.

30. Covers and protects the leaf.

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

32. Is the sugar that lactase acts upon.

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

34. Proposes that those individuals within a population that are most adapted to the environment are also the most likely individuals to produce viable offspring.

35. What phylum are snakes in?

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

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

38. 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

39. Is a substance that changes the speed of a reaction without being affected itself.

40. Contains optic lobes - controls sight.

41. Are the organelles where cellular respiration occurs.

42. The process of forming eggs and sperm cells in the reproductive organs.

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

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

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

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

47. 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.

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

49. Internally generated patterns of body functions - including hormonal signals - sleep - blood pressure - and temperature regulation - which have approximately a 24-hour cycle and occur even in the absence of normal cues about whether it is day or nigh

50. Has extreme hot or cold temperatures - with very low precipitation - sandy or rocky terrain - sparse vegetation (mainly succulents) - small animals - rodents - and reptiles.
