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 a phylum that contains sponges.






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






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






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






5. It secretes saliva which enters the digestive tract and aids the digestive process.






6. Is the waxy protective outer coating of leaves.






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






8. The phyla of sponges.






9. In DNA Thymine pairs with...






10. 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






11. In DNA Guanine pairs with...






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






13. Is found in the root cap and is responsible for quick growth in the roots.






14. 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.






15. Bacteria break ammonia into nitrites - then into nitrates that are usable by plants; volcanic activity produces ammonia and nitrates that enter the soil and can be absorbed by plants; lightning reacts with atmospheric nitrogen to form nitrates that a






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






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






18. Covers and protects the leaf.






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






20. The systematic search for individuals with a specific genotype in a delineated population.






21. Cleave strands of DNA segments at certain sites.






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






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






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






26. The class composed of birds.






27. 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.






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






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






30. Biotic (living) factors such as population and food source - and abiotic (non-living) factors such as weather - temperature - soil features - sunlight).






31. 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.






32. Ended with the extinction of the dinosaurs.

34. Plants and animals obtain usable nitrogen






35. Is the major component of sand and is the most abundant element found in the lithosphere. It is not recycled.






36. High temperatures






37. A suffix meaning 'to break apart.' O || ||






38. The transfer of electrons.






39. 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






40. Disease causing






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






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






43. Occurs when two populations are geographically isolated from each other. Over time this results in the production of two separate species.






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