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






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






3. Has loosely packed cells that allow for gas and moisture exchange.






4. The sharp boundary of an ecosystem.






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






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






7. Produce adrenaline. This hormone is a well-known constrictor of blood vessels.






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






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






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






11. Is the outermost of the three main layers of an embryo.






12. Is a phylum that contains sponges.






13. 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.






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






15. Inorganic phosphate






16. All store energy within their chemical bonds.






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






18. 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).






19. The phyla of round worms.






20. Carbon - Hydrogen - Oxygen - and Nitrogen






21. Is a kingdom that includes algae and protozoa.






22. The process of forming eggs and sperm cells in the reproductive organs.






23. The phyla of sponges.






24. Is the organelle where cellular reproductive processes occur.






25. High temperatures






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






27. In both living and non-living environments.






28. 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.






29. Develops from the morula as a thin layer of cells surrounding an internal cavity.






30. Cleave strands of DNA segments at certain sites.






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






32. Disease causing






33. 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.






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






35. The lineage that led to the modern Homo Sapiens diverged from the lineage that led to the modern chimpanzee.






36. Contains multicellular photosynthetic eukaryotic organisms including gymnosperms and angiosperms.






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






38. Is disorganized - unravelled - DNA with histones attached.






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






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






41. Contains optic lobes - controls sight.






42. The part of the earth that contains all living things - including the atmosphere (air) - the lithosphere (earth) - and the hydrosphere (water).






43. This is a carboxyl group and is the signature group found within organic acids.






44. Breaking down






45. The class composed of birds.






46. Niche






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






48. 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.






49. An enzyme is unaffected by the reactions it catalyzes






50. 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.
