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. Super-class of vertebrae including organisms with jaws.






2. Enzymes are usually __________ to certain reactions.






3. 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.






4. The phylum of insects (bees).






5. 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.






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






7. Is the organelle where cellular reproductive processes occur.






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






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






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






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






12. Respiratory organs within insects






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






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






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






16. Contains the chromosomes and is the site of reproduction through mitosis and meiosis.






17. Engages in both passive and active transport.






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






19. 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).






20. Is found on the stem between nodes.






21. A sex-linked recessive disorder carried on the x chromosome in which an individual cannot perceive certain colors.






22. Plants and animals obtain usable nitrogen






23. Proposes that those individuals within a population that are most adapted to the environment are also the most likely individuals to produce viable offspring.






24. Is a kingdom that includes algae and protozoa.






25. A hydrogen bond involves the ________________ and can be easily broken.






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






27. Becomes available for erosion as undersea sedimentary rocks are up-thrust by volcanic activity - erosion releases it from rocks into streams where it combines with oxygen to form phosphates in lakes that are then absorbed by plants - it is recycled t






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






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






30. Cleave strands of DNA segments at certain sites.






31. Produce seeds without flowers. They include conifers (cone-bearers) and cycads.






32. Synthesis






33. 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).






34. An opportunistic life strategy strategy. Lichens invading a bare rock area after a volcanic eruption is an example.






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






36. 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.






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






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






39. Is a phylum that contains sponges.






40. The pituitary gland.






41. The size of a cell is limited by the ratio of its surface area to volume.






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






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






44. The phyla composed of segmented worms.






45. High temperatures






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






47. In DNA Guanine pairs with...






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






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






50. The sharp boundary of an ecosystem.
