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. Process in which elements - chemical compounds - and other forms of matter are passed from one organism to another and from one part of the biosphere to another.






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






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






4. Niche






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. Some energy is lost as heat and becomes unusable.






7. Covers and protects the leaf.






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






9. 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.






10. Synthesis






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






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






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






14. 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.






15. Most chemical pollutants accidentally ingested by humans are __________ - mixed with broken down pigments in the bile - then bile is secreted into the small intestine - proceeds to the large intestine - and is expelled in the feces.






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






17. 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.






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






19. In DNA Thymine pairs with...






20. Protein synthesis






21. In DNA Guanine pairs with...






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






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






24. Is a protein - which is a polymer of amino acids. They generally have the suffix -ase- like lactase.






25. The sharp boundary of an ecosystem.






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






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






28. Is a phylum that contains sponges.






29. All store energy within their chemical bonds.






30. An orienting response to light.






31. The phylum of insects (bees).






32. Is a packet of digestive enzymes that destroy cellular wastes.






33. Is the outermost layer of cells of the stem.






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






35. High temperatures






36. Respiratory organs within insects






37. The transfer of electrons.






38. 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






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






40. Covalent bonds






41. 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






42. Provide rigidity to plant cells (and some bacteria) and are not found within animal cells.






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






44. 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






45. 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






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






47. 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.






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






49. The phyla of round worms.






50. Is the organelle where cellular reproductive processes occur.
