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. Super-class of vertebrae including organisms with jaws.






3. Layer that will become the gut lining as well as some accessory structures.






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






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






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






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






8. Small - green - heart-shaped gametophyte plant form of a fern that can make its own food and absorb water and nutrients from the soil






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






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






11. 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).






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






13. Is the organelle where cellular reproductive processes occur.






14. Where protein synthesis occurs. They float unattached in the cytoplasm. They contain RNA that is specific to their function in protein formation.






15. An enzyme is unaffected by the reactions it catalyzes






16. Inorganic phosphate






17. Are the organelles where cellular respiration occurs.






18. 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.






19. Algae and Protozoa belong to the kingdom...






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






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






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






23. 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






24. 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.






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






26. The pituitary gland.






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






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






29. Can be accounted for by the theory of punctuated equilibrium. The fossil record shows periods of stability with regard to appearance and disappearance of species as well as periods of sudden change.






30. High temperatures






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






32. Niche






33. 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






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






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






36. 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






37. Layer that will become the skin - some endocrine glands - and the nervous system.






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






39. 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.






40. 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.






41. A reaction that adds water to another compound. (2 hydrogens - 1 oxygen).






42. The most recent and present era. It includes the radiation of flowering plants - the angiosperms.






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






44. Is a coenzyme required in the synthesis of collagen.






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






46. Is a compound fruit that forms from several ovaries of separate flowers that fuse together during ripening (strawberry - or pineapple).






47. 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.






48. Produce antibodies into the bloodstream that find and attach themselves to foreign antigens (toxins - bacteria).






49. Is the sugar that lactase acts upon.






50. The transfer of electrons.
