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






2. The phylum of insects (bees).






3. Secretes insulin to lower blood sugar and maintain equilibrium. A person eats three candy bars. Within minutes this endocrine gland affects blood-glucose homeostasis.






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






5. 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).






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






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






8. Controls hunger and thirst






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






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






11. Are the organelles where cellular respiration occurs.






12. 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.






13. Controls olfactory lobes (smell)






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






15. The sharp boundary of an ecosystem.






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






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






18. Can be accounted for by the theory of punctuated equilibrium. The fossil record shows periods of stability with regard to appearance and disappearance of species as well as periods of sudden change.






19. Are where the sugars synthesized by photosynthesis travel through to various parts of the plant.






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






21. Fruits that develop from a single ripened ovary (apple - olive - acorn - cucumber).






22. In order to become an established part of an island ecosystem there must be a populations large enough to ensure _________ - a food source - a suitable habitat - and a source of moisture.






23. Are surrounded by capillaries that allow for carbon dioxide to diffuse into the lungs and oxygen to diffuse out.






24. Is found on the stem between nodes.






25. Refers to the birthrate of a population.






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






27. 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.






28. The phyla of sponges.






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






30. Subsets below the kingdom level






31. A cell will only remain stable if the surface area of the plasma membrane maintains a __________ with the volume of the cytoplasm.






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






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






34. 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.






35. 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.






36. Is a kind of plain characterized by a warm climate - grassland - and seasonally dry climate conditions.






37. Respiratory organs within insects






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






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






40. Carbon - Hydrogen - Oxygen - and Nitrogen






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






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






43. The individual we recognize as an adult fern.






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






45. The pituitary gland.






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

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






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






49. Is the outermost of the three main layers of an embryo.






50. Contain organisms that are multicellular eukaryotes including vertebrates and invertebrates.
