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 process whereby cells build molecules and store energy (in the form of covalent chemical bonds).






2. Is weaker than ionic - covalent - disulfide - or double bonds.






3. Has extreme hot or cold temperatures - with very low precipitation - sandy or rocky terrain - sparse vegetation (mainly succulents) - small animals - rodents - and reptiles.






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






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






6. Is the organelle where cellular reproductive processes occur.






7. 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






8. Consists of undifferentiated cells capable of quick growth and specialization. It is responsible for elongation of the stem.






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






10. Developed by the German scientists Schleiden and Schwann - States that all living things are made of cells - cells are the basic units of life - all cells come from pre-existing cells.






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






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






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






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






15. Super-class of vertebrae including organisms with jaws.






16. 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.






17. 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






18. Is the sugar that lactase acts upon.






19. Occurs when an individual learns not to respond to a particular stimulus - for instance when a stimulus is repeated many times without consequence.






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






21. 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.






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






23. 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.






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






25. Are where the sugars synthesized by photosynthesis travel through to various parts of the plant.






26. Synthesis






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






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






29. Is the waxy protective outer coating of leaves.






30. Engages in both passive and active transport.






31. 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.






32. The phyla composed of segmented worms.






33. Is a phylum that contains sponges.






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






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






36. Cleave strands of DNA segments at certain sites.






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






38. Covers and protects the leaf.






39. Internally generated patterns of body functions - including hormonal signals - sleep - blood pressure - and temperature regulation - which have approximately a 24-hour cycle and occur even in the absence of normal cues about whether it is day or nigh






40. High temperatures






41. Is a disease caused by lack of vitamin C in which the body is unable to build enough collagen (a major component of connective tissue).






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






43. There was extensive radiation of fish during the Devonian and Silurian periods within the Paleozoic Era.






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






45. The phyla of round worms.






46. Are more closely related to Homo Sapiens than to other apes - but Homo Sapiens did not evolve from chimpanzees.






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






48. 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.






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






50. Absorb a photon of light and is found in the grana of the chloroplast.
