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. Is the earliest period of the Paleozoic era. Began with the Cambrian explosion - this explosion of life resulted in the representatives of most of the modern phyla being present.






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






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






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






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






6. Contains many genes and is a structure comprised of linear DNA and associated proteins.






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






8. Carbon - Hydrogen - Oxygen - and Nitrogen






9. The pituitary gland.






10. 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






11. What phylum are snakes in?






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






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






14. 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.






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






16. Transfers water and does not require sieve plates to allow nutrients through.






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






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






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






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






21. The phyla of round worms.






22. Algae and Protozoa belong to the kingdom...






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






24. 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






25. 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.






26. 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.






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






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






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






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






31. When the water concentration inside and outside the cell is equal - It is said to be in an...






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






33. (of some plants or fungi) feeding on dead or decaying organic matter






34. Breaking down






35. Is composed of an anterior and posterior lobe. The stalk of the lobe is connected to the hypothalamus. Antidiuretic Hormone (AH) is produced in the hypothalamus and stored in the posterior pituitary. Upon nervous stimulation from the hypothalamus - t






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






37. An orienting response to light.






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






39. 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.






40. 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






41. Is a phylum that contains sponges.

46. The solid mass of cells resulting from the cleavage of the ovum before the formation of a blastula.






47. 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






48. In DNA Guanine pairs with...






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






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