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. High temperatures






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






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






4. Contains optic lobes - controls sight.






5. Is a protein - which is a polymer of amino acids. They generally have the suffix -ase- like lactase.






6. Is the waxy protective outer coating of leaves.






7. Contains organisms that are multicellular eukaryotes including molds and mushrooms.






8. The sharp boundary of an ecosystem.






9. Is a phylum that contains sponges.






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






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






12. Assumes that there are periods of stability during which little evolutionary change occurs - and that speciation can occur rapidly over a very short period of time.






13. Is found on the stem between nodes.






14. The phyla of sponges.






15. Controls olfactory lobes (smell)






16. Are the organelles where cellular respiration occurs.






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






18. 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.






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






20. The physical place where a particular organism lives. It must include all the factors that will support its life and reproduction.






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






22. 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.






23. Biotic (living) factors such as population and food source - and abiotic (non-living) factors such as weather - temperature - soil features - sunlight).






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






25. 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.






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






27. Covers and protects the leaf.






28. Where protein synthesis occurs. They float unattached in the cytoplasm. They contain RNA that is specific to their function in protein formation.






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






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






31. Decomposition of living matter for consumption.






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






33. Subsets below the kingdom level






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






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






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






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






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






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






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






41. Produce seeds without flowers. They include conifers (cone-bearers) and cycads.






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






43. Cleave strands of DNA segments at certain sites.






44. Controls hunger and thirst






45. 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.






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






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






48. Ended with the extinction of the dinosaurs.






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






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