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. 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.






2. Are produced when water passes through the cell membrane by osmosis from an area of higher concentration to an area of lower concentration - to equalize water concentration.






3. 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






4. Disease causing






5. In both living and non-living environments.






6. A length of DNA (with corresponding histones) is responsible for the production of a certain protein that causes a particular trait to be expressed in an organism.






7. 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.






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. The pharynx is between the nasal passage and the trachea. Air passes into the body via the nasal passage - then passes through the pharynx and on to the trachea.






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






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






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






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






14. Engages in both passive and active transport.






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






16. The individual we recognize as an adult fern.






17. Breaking down






18. The size of a cell is limited by the ratio of its surface area to volume.






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






20. Is the control of protein synthesis. Genetic traits are expressed and specialization of cells occur as a result of the combination of proteins produced by the DNA of a cell.






21. It secretes saliva which enters the digestive tract and aids the digestive process.






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






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






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






25. Provide rigidity to plant cells (and some bacteria) and are not found within animal cells.






26. Covalent bonds






27. A reaction that adds water to another compound. (2 hydrogens - 1 oxygen).






28. Controls hunger and thirst






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






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






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






32. 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.






33. 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.






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






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






36. Produce adrenaline. This hormone is a well-known constrictor of blood vessels.






37. Super-class of vertebrae including organisms with no jaws.






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






39. Is a compound fruit that forms from several ovaries of separate flowers that fuse together during ripening (strawberry - or pineapple).






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






41. Contains optic lobes - controls sight.






42. 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).






43. Process in which elements - chemical compounds - and other forms of matter are passed from one organism to another and from one part of the biosphere to another.






44. States that where random mating is occurring within a population that is in equilibrium with its environment - the gene frequencies and genotype ratios will remain constant from generation to generation. It is a mathematical formula that shows why re






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






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






47. Produces the most ATP molecules - yielding 34 ATPs per glucose molecule.






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






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






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