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. Some energy is lost as heat and becomes unusable.






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






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






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






5. 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.






6. 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.






7. Is a phylum that contains sponges.






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






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






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






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






12. Is the organelle where cellular reproductive processes occur.






13. What phylum are snakes in?






14. The phyla of sponges.






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






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






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






18. The sharp boundary of an ecosystem.






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






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






21. Is found in the root cap and is responsible for quick growth in the roots.






22. Is an abundant element found in protoplasm. Together with oxygen - hydrogen - and nitrogen - it composes over 90% of cellular structure.






23. 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






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






25. Anabolism






26. Approximately 7 - making it neither basic (under 7) nor alkaline (over 7).






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






28. 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






29. 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.






30. The part of the earth that contains all living things - including the atmosphere (air) - the lithosphere (earth) - and the hydrosphere (water).






31. Protein synthesis






32. 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






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






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






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






36. The process of forming eggs and sperm cells in the reproductive organs.






37. Is very rare and is not absorbed by plant leaves. Phosphorous is nearly always found in solid form.






38. Controls hunger and thirst






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






40. Controls balance and muscle coordination






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






42. The class composed of birds.






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






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






45. Is a special protein that acts as a catalyst for organic reactions.






46. 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






47. 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.






48. 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






49. Controls olfactory lobes (smell)






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