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






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






3. Contains optic lobes - controls sight.






4. 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.






5. This is a carboxyl group and is the signature group found within organic acids.






6. High temperatures






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






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






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






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






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






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






13. Covers and protects the leaf.






14. Has extreme cold temperatures - low precipitation - modified grassland - perma-frost - a short growing season and some plants and animals.






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






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






17. 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.






18. Has an equal (50%) chance of being passed from a carrier mother to a son or a daughter.






19. 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.






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






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






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






23. Nonvascular plants such as mosses which lack tissue for conducting food or water.






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






25. Is the organelle where cellular reproductive processes occur.






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






27. Energy transformations that occur as chemicals are broken down or synthesized within the cell.






28. Produce antibodies into the bloodstream that find and attach themselves to foreign antigens (toxins - bacteria).






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






30. 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.






31. The most recent and present era. It includes the radiation of flowering plants - the angiosperms.






32. Engages in both passive and active transport.






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






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






35. 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.






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






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






38. The individual we recognize as an adult fern.






39. The destruction of gametes - (sex cells such as sperm and eggs).






40. Has loosely packed cells that allow for gas and moisture exchange.






41. The effect of a substrate concentration on the initial reaction rate in the presence of a limited amount of enzyme: _________________ as the concentration of substrate is increased until all the enzymes are used - then the reaction rate will level of






42. The total amount of genetic information available for a given species.






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






44. Subsets below the kingdom level






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






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






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






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






49. Plants and animals obtain usable nitrogen






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