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






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






3. 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






4. Is a kingdom that includes algae and protozoa.






5. Are cells involved in immunity and are produced in bone marrow as stem cells.






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






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






8. Is a special protein that acts as a catalyst for organic reactions.






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






10. Is a social behavior of an organism that is beneficial to the group at the individual's expense.






11. Is a phylum that contains sponges.






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






13. 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.






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






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






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






17. 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.






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






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






20. Ended with the extinction of the dinosaurs.






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






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






23. A length of DNA (with corresponding histones) is responsible for the production of a certain protein that causes a particular trait to be expressed in an organism.






24. 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.






25. Controls olfactory lobes (smell)






26. High temperatures






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






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






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






30. Contains organisms that are multicellular eukaryotes including molds and mushrooms.






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






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






33. 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.






34. Enzymes are usually __________ to certain reactions.






35. Is more like branching out of a tree with dead ends and new branches appearing simultaneously than like steps on a ladder.






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






37. The class composed of birds.






38. 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).






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






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






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






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






43. All store energy within their chemical bonds.






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






45. The number of organisms in a given community - can be above or below the carrying capacity.






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






47. 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






48. Has an equal (50%) chance of being passed from a carrier mother to a son or a daughter.






49. Most fossils of Hominids are from continents other than...






50. The individual we recognize as an adult fern.
