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 of forming eggs and sperm cells in the reproductive organs.






2. Subsets below the kingdom level






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






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






5. Occurs when two populations are geographically isolated from each other. Over time this results in the production of two separate species.






6. 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






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






8. Ended with the extinction of the dinosaurs.






9. Stood upright before there was an increase in brain size.






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






11. Must be present for photosynthesis to occur - it is not used up in the process.






12. In both living and non-living environments.






13. Channels is cell membranes that carry water between cells.






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






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






16. The phyla of round worms.






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






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






19. The vocal cords are found in the larynx.






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






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






22. Inorganic phosphate






23. Controls hunger and thirst






24. Is a kind of plain characterized by a warm climate - grassland - and seasonally dry climate conditions.






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






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






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






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






29. Include: Vascular tissue - including both xylem and phloem - and sieve plates existing between cells of the stem.






30. Controls balance and muscle coordination






31. Covers and protects the leaf.






32. Is secreted by the adrenal cortex to promote sodium reabsorption in the kidney.






33. 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.






34. Are cells involved in immunity and are produced in bone marrow as stem cells.






35. All store energy within their chemical bonds.






36. Is the outermost of the three main layers of an embryo.






37. Process in which elements - chemical compounds - and other forms of matter are passed from one organism to another and from one part of the biosphere to another.






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






39. The transfer of electrons.






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






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






42. 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.






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






44. Plants and animals obtain usable nitrogen






45. Bacteria break ammonia into nitrites - then into nitrates that are usable by plants; volcanic activity produces ammonia and nitrates that enter the soil and can be absorbed by plants; lightning reacts with atmospheric nitrogen to form nitrates that a






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






47. Sex-linked recessive disorder carried on the x chromosome defined by the absence of one or more proteins required for blood clotting






48. 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






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






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