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. Is the control of protein synthesis. Genetic traits are expressed and specialization of cells occur as a result of the combination of proteins produced by the DNA of a cell.






2. All store energy within their chemical bonds.






3. Is comprised of all the organisms that interact within a given ecosystem whether or not it is at carrying capacity.






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






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






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






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






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






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






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






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






13. Is an accidental change of the DNA sequence of the gene that can result in creating a change of trait that is not found in the parent.






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






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






16. 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.






17. Is the sugar that lactase acts upon.






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






19. 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.






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






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






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






23. Is composed of a double layer (bilayer) of phospholipids with protein globules imbedded within the layers. The construction of the membrane allows it to aid the function of the cell by permitting entrance and exit of molecules as needed by the cell.






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






25. When stems bend toward the light it is due to _____________ the hormone auxin - in response to light - migrates from the light to the dark side of the shoot tip. The cells on the dark side now contain more auxin - which causes the cells on that side






26. 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






27. The vocal cords are found in the larynx.






28. The trachea includes the windpipe or larynx in its upper portion - and the glottis - an opening that allows the gases to pass into the two branches known as the bronchi.






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






30. Transfers water and does not require sieve plates to allow nutrients through.






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






32. Is the period when the cell is active in carrying on the function it was designed to perform within the organism. Cells spend much more time in interphase than in cell division.






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






34. Is a kingdom that includes algae and protozoa.






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






36. An enzyme is unaffected by the reactions it catalyzes






37. High temperatures






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






39. Covers and protects the leaf.






40. 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






41. Most fossils of Hominids are from continents other than...






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






43. Inorganic phosphate






44. 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






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






46. Veins in the leaf and are also distributed throughout the stem






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






48. 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.






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






50. The transfer of electrons.
