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






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






3. Is a compound fruit that develops from many ovaries of a single flower fusing together (raspberry).






4. An enzyme is unaffected by the reactions it catalyzes






5. 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






6. The pituitary gland.






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






8. A reaction that adds water to another compound. (2 hydrogens - 1 oxygen).






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






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






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






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






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






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






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






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






17. Covers and protects the leaf.






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






19. The lineage that led to the modern Homo Sapiens diverged from the lineage that led to the modern chimpanzee.






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






21. Contains optic lobes - controls sight.






22. The bronchi lead to the two lungs where they branch out in all directions into smaller tubules known as bronchioles.






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






24. Where protein synthesis occurs. They float unattached in the cytoplasm. They contain RNA that is specific to their function in protein formation.






25. Is found on the stem between nodes.






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






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






28. 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






29. The solid mass of cells resulting from the cleavage of the ovum before the formation of a blastula.






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






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






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






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






34. 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.






35. Anabolism






36. In order to become an established part of an island ecosystem there must be a populations large enough to ensure _________ - a food source - a suitable habitat - and a source of moisture.






37. This is a carboxyl group and is the signature group found within organic acids.






38. 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).






39. Allows for the genetic code to be preserved in future generations of cells.






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






41. 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






42. A cell will only remain stable if the surface area of the plasma membrane maintains a __________ with the volume of the cytoplasm.






43. What phylum are snakes in?






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






45. Controls hunger and thirst






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






47. Are membrane-bound organelles that contain digestive enzymes that digest dead or unused material within the cell or materials absorbed by the cell for use.






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






49. The transfer of electrons.






50. Is the sugar that lactase acts upon.
