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. In DNA Guanine pairs with...






2. 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






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






4. 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).






5. 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.






6. Occurs when an individual learns not to respond to a particular stimulus - for instance when a stimulus is repeated many times without consequence.






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






8. The process whereby cells build molecules and store energy (in the form of covalent chemical bonds).






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






10. Is found in the root cap and is responsible for quick growth in the roots.






11. The phyla composed of segmented worms.






12. 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






13. The class composed of birds.






14. 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.






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






16. The phyla of round worms.






17. The phylum of insects (bees).






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






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






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






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






22. 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.






23. Is found on the stem between nodes.






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






25. (of some plants or fungi) feeding on dead or decaying organic matter






26. Niche






27. Carbon - Hydrogen - Oxygen - and Nitrogen






28. Respiratory organs within insects






29. Is the sugar that lactase acts upon.






30. Controls balance and muscle coordination






31. 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






32. Controls olfactory lobes (smell)






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






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






35. The phyla of sponges.






36. May be ions or non-protein molecules - they are similar to cofactors - but differ in that they are tightly attached by covalent bonds to the enzyme - rather than being separate atoms or molecules.






37. Plants that produce flowers as reproductive organs. They have two divisions - monocots and dicots.






38. 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.






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






40. 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






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






42. The physical place where a particular organism lives. It must include all the factors that will support its life and reproduction.






43. High temperatures






44. The systematic search for individuals with a specific genotype in a delineated population.






45. In DNA Thymine pairs with...






46. 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.






47. Are easily converted to ATP - but the main energy products of the Krebs cycle liberate electrons then used in the electron transfer reactions.






48. Small - green - heart-shaped gametophyte plant form of a fern that can make its own food and absorb water and nutrients from the soil






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






50. Is the waxy protective outer coating of leaves.
