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. Developed by the German scientists Schleiden and Schwann - States that all living things are made of cells - cells are the basic units of life - all cells come from pre-existing cells.






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






4. Protein synthesis






5. Contains optic lobes - controls sight.






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






7. Process of breaking down complex materials (foods) to form simpler substances and release energy.






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






9. The class composed of birds.






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






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






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






13. Are formed when the plasma membrane of a cell encloses a molecule outside the membrane - then releases a membrane bound sack containing the desired molecule into the cytoplasm. This process allows the cell to absorb molecules that are larger in size






14. Carbon - Hydrogen - Oxygen - and Nitrogen






15. Are tubes constructed of a geometrical arrangement of microtubules in a pinwheel shape. Their function includes the formation of new microtubules - but is primarily to form the structural skeleton around which cells split during mitosis and meiosis.






16. 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






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






18. 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.






19. The process whereby cells build molecules and store energy (in the form of covalent chemical bonds).






20. Between the endoderm and ectoderm - layer that will eventually form the muscles - and organs of the skeletal - circulatory - respiratory - reproductive - and excretory systems.






21. 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.






22. The phylum of insects (bees).






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






24. Is a kingdom that includes algae and protozoa.






25. Occurs when an individual from an adjacent population of the same species immigrates and breeds with a member of a previously locally isolated group - resulting in a change in the gene pool.






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






27. The vocal cords are found in the larynx.






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






29. Is an ion that binds to an enzyme making it more able to catalyze a reaction.






30. Contain one celled eukaryotes such as algae and protozoa.






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






32. Is composed of a double layer (bilayer) of phospholipids with protein globules imbedded within the layers. The construction of the membrane allows it to aid the function of the cell by permitting entrance and exit of molecules as needed by the cell.






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






34. 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.






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






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






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






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






39. 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.






40. 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.






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






42. Is the sugar that lactase acts upon.






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






44. What phylum are snakes in?






45. The phyla of round worms.






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






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






48. Engages in both passive and active transport.






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






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