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. Are the monomers that form nucleic acids - containing a sugar - phosphate group - and a nitrogenous base.

2. An orienting response to light.

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

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

5. An enzyme is unaffected by the reactions it catalyzes

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

7. 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.

8. The pituitary gland.

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

10. Decomposition of living matter for consumption.

11. The phyla of sponges.

12. Is an ion that binds to an enzyme making it more able to catalyze a reaction.

13. Controls hunger and thirst

14. 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

15. Where protein synthesis occurs. They float unattached in the cytoplasm. They contain RNA that is specific to their function in protein formation.

16. The phyla of round worms.

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

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

19. 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).

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

21. Is the organelle where cellular reproductive processes occur.

22. Is a protein - which is a polymer of amino acids. They generally have the suffix -ase- like lactase.

23. Covalent bonds

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

25. Process of breaking down complex materials (foods) to form simpler substances and release energy.

26. Ended with the extinction of the dinosaurs.

27. Most fossils of Hominids are from continents other than...

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

29. Are the organelles where cellular respiration occurs.

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

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

32. Anabolism

33. The lineage that led to the modern Homo Sapiens diverged from the lineage that led to the modern chimpanzee.

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

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

37. Refers to the birthrate of a population.

38. Includes all living and nonliving components of the Earth to support living things.

39. The individual we recognize as an adult fern.

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

41. Breaking down

42. Fossilized burrows from multicellular organisms begin to appear in the geological record approximately 700 million years ago during the Precambrian period. These multicellular animals had only soft parts and could not be fossilized.

43. Approximately 7 - making it neither basic (under 7) nor alkaline (over 7).

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

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

46. 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.

47. Include: Vascular tissue - including both xylem and phloem - and sieve plates existing between cells of the stem.

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

49. 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.

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