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






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






3. Controls olfactory lobes (smell)






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






5. The destruction of gametes - (sex cells such as sperm and eggs).






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






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






8. Is the waxy protective outer coating of leaves.






9. Synthesis






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






11. Has extreme hot or cold temperatures - with very low precipitation - sandy or rocky terrain - sparse vegetation (mainly succulents) - small animals - rodents - and reptiles.






12. 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.






13. 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.






14. 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.






15. The phyla composed of segmented worms.






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






17. Absorb a photon of light and is found in the grana of the chloroplast.






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






19. Cleave strands of DNA segments at certain sites.






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






21. All store energy within their chemical bonds.






22. 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.






23. Is a phylum that contains jellyfish - hydra - etc.






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






25. Niche






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






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






28. Decomposition of living matter for consumption.






29. Subsets below the kingdom level






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






31. The class composed of birds.






32. An enzyme is unaffected by the reactions it catalyzes






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






34. 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






35. High temperatures






36. Is the number of organisms that can be supported within a particular ecosystem.






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






38. 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






39. Anabolism






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






41. The phylum of insects (bees).






42. Contains optic lobes - controls sight.






43. The individual we recognize as an adult fern.






44. Covers and protects the leaf.






45. Is made of stacked cells connected by sieve plates that allow nutrients to pass from cell to cell. They transport food made in the leaves (by photosynthesis) to the rest of the plant).






46. 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






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






48. Enzymes are usually __________ to certain reactions.






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






50. 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).
