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. Are the organelles where cellular respiration occurs.






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






3. Controls olfactory lobes (smell)






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






5. When the water concentration inside and outside the cell is equal - It is said to be in an...






6. The cells of a developing embryo (at the gastrula stage) differentiate into layers - that will later develop into different tissues and organs - including the mesoderm - ectoderm - and endoderm.






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






8. Decomposition of living matter for consumption.






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






10. 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






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






12. Subsets below the kingdom level






13. 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.






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






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






16. The transfer of electrons.






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






18. The pituitary gland.






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






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






21. High temperatures






22. Niche






23. Is found on the stem between nodes.






24. Is a phylum that contains sponges.






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






26. 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.






27. 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






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






29. Attaches to an enzyme and blocks the enzyme reaction rather than enhancing it - like a prosthetic group would.






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






31. The vocal cords are found in the larynx.






32. Provide rigidity to plant cells (and some bacteria) and are not found within animal cells.






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






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






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






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






37. 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






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






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






40. Refers to the birthrate of a population.






41. The number of organisms in a given community - can be above or below the carrying capacity.






42. All store energy within their chemical bonds.






43. In DNA Thymine pairs with...






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






45. 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.






46. Protein synthesis






47. Are tubes constructed of a geometrical arrangement of microtubules in a pinwheel shape. Their function includes the formation of new microtubules - but is primarily to form the structural skeleton around which cells split during mitosis and meiosis.






48. Enzymes are usually __________ to certain reactions.






49. The phylum of insects (bees).






50. Covers and protects the leaf.
