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. In DNA Thymine pairs with...






2. All store energy within their chemical bonds.






3. Controls balance and muscle coordination






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






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






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






7. 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






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






9. Controls olfactory lobes (smell)






10. Channels is cell membranes that carry water between cells.






11. 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.






12. Is found on the stem between nodes.






13. Most chemical pollutants accidentally ingested by humans are __________ - mixed with broken down pigments in the bile - then bile is secreted into the small intestine - proceeds to the large intestine - and is expelled in the feces.






14. 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.






15. Synthesis






16. The transfer of electrons.






17. Cleave strands of DNA segments at certain sites.






18. Is a phylum that contains sponges.






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






20. The phyla of sponges.






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






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






23. High temperatures






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






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






26. Inorganic phosphate






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






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






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






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






31. Enzymes are usually __________ to certain reactions.






32. 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.






33. 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.






34. Is a phylum that contains jellyfish - hydra - etc.






35. Is found in the root cap and is responsible for quick growth in the roots.






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






37. Chlorophyll pigments absorb photons of light - leaving the chlorophyll in a higher energy (excited) state - these then supply energy to reactions that produce ATP from ADP and Pi.






38. The sharp boundary of an ecosystem.






39. Is the major component of sand and is the most abundant element found in the lithosphere. It is not recycled.






40. Is the process that releases energy for use by the cell.






41. The class composed of birds.






42. Is a behavior that is learned during a critical point (often very early) in an individual's life. Imprinting enables the young the recognize members of their own species.






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






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






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






46. 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.






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






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






49. Is a social behavior of an organism that is beneficial to the group at the individual's expense.






50. 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.
