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 organelles where cellular respiration occurs.






2. Super-class of vertebrae including organisms with no jaws.






3. 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.






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






5. Synthesis






6. Engages in both passive and active transport.






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






8. 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.






9. 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.






10. 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.






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






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






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






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






15. 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.






16. The transfer of electrons.






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






18. The role played by an organism in its food chain.






19. 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).






20. Controls sensory and motor responses - and controls memory - speech - and intelligence factors.






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






22. The bronchi lead to the two lungs where they branch out in all directions into smaller tubules known as bronchioles.






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






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






25. Controls olfactory lobes (smell)






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






27. Refers to the birthrate of a population.






28. The class composed of birds.






29. Is very rare and is not absorbed by plant leaves. Phosphorous is nearly always found in solid form.






30. High temperatures






31. Contains many genes and is a structure comprised of linear DNA and associated proteins.






32. Is a kingdom that includes algae and protozoa.






33. States that where random mating is occurring within a population that is in equilibrium with its environment - the gene frequencies and genotype ratios will remain constant from generation to generation. It is a mathematical formula that shows why re






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






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






36. The phyla of round worms.






37. 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.






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






39. Fruits that develop from a single ripened ovary (apple - olive - acorn - cucumber).






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






41. The total amount of genetic information available for a given species.






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






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






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






45. 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.






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






47. Transparency - polarity - high specific heat - and density (lower density when solid than when liquid.).






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






49. Is an abundant element found in protoplasm. Together with oxygen - hydrogen - and nitrogen - it composes over 90% of cellular structure.






50. Is a phylum that contains jellyfish - hydra - etc.
