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






2. Subsets below the kingdom level






3. Secretes insulin to lower blood sugar and maintain equilibrium. A person eats three candy bars. Within minutes this endocrine gland affects blood-glucose homeostasis.






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






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






6. High temperatures






7. Most chemical pollutants accidentally ingested by humans are __________ - mixed with broken down pigments in the bile - then bile is secreted into the small intestine - proceeds to the large intestine - and is expelled in the feces.






8. Decomposition of living matter for consumption.






9. Some patrol the blood for antigens - but are also equipped to destroy antigens. They may regulate immune responses as well.






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






11. Covers and protects the leaf.






12. Are surrounded by capillaries that allow for carbon dioxide to diffuse into the lungs and oxygen to diffuse out.






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






14. Some energy is lost as heat and becomes unusable.






15. The pharynx is between the nasal passage and the trachea. Air passes into the body via the nasal passage - then passes through the pharynx and on to the trachea.






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






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






18. An orienting response to light.






19. Protein synthesis






20. Controls balance and muscle coordination






21. Niche






22. Process of breaking down complex materials (foods) to form simpler substances and release energy.






23. Synthesis






24. Is found on the stem between nodes.






25. Ended with the extinction of the dinosaurs.






26. 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






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






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






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






30. The phyla of sponges.






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






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






33. Is a kingdom that includes algae and protozoa.






34. Is composed of an anterior and posterior lobe. The stalk of the lobe is connected to the hypothalamus. Antidiuretic Hormone (AH) is produced in the hypothalamus and stored in the posterior pituitary. Upon nervous stimulation from the hypothalamus - t






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






36. Transparency - polarity - high specific heat - and density (lower density when solid than when liquid.).






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






38. Is a molecule that stores information for protein synthesis and genetic coding.






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






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






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






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






43. 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.






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






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






46. Contain one celled eukaryotes such as algae and protozoa.






47. Contains multicellular photosynthetic eukaryotic organisms including gymnosperms and angiosperms.






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






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






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