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






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. 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.






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






5. Digestive enzymes - hydrochloric acid - and gastric juices which aid in digestion. The mucous secreted by the stomach protects the stomach lining from the acids and juices.






6. Are where the sugars synthesized by photosynthesis travel through to various parts of the plant.






7. Fossilized burrows from multicellular organisms begin to appear in the geological record approximately 700 million years ago during the Precambrian period. These multicellular animals had only soft parts and could not be fossilized.






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






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






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






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






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






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






14. Enzymes are usually __________ to certain reactions.






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






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






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






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






19. Assumes that there are periods of stability during which little evolutionary change occurs - and that speciation can occur rapidly over a very short period of time.






20. 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






21. 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.






22. Controls balance and muscle coordination






23. In DNA Thymine pairs with...






24. Is a phylum that contains sponges.






25. Are the organelles where cellular respiration occurs.






26. 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).






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






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






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






30. 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).






31. An enzyme is unaffected by the reactions it catalyzes






32. Respiratory organs within insects






33. The solid mass of cells resulting from the cleavage of the ovum before the formation of a blastula.






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






35. 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.






36. The class composed of birds.






37. In DNA Guanine pairs with...






38. Decomposition of living matter for consumption.






39. All store energy within their chemical bonds.






40. Engages in both passive and active transport.






41. Plants and animals obtain usable nitrogen






42. 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.






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






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






45. The phyla of sponges.






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






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






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






49. Carbon - nitrogen - phosphorous - and water. These are all recycled through biogeochemical processes.
