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. Subsets below the kingdom level






2. Covers and protects the leaf.






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






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






5. Plants that produce flowers as reproductive organs. They have two divisions - monocots and dicots.






6. The cells of a developing embryo (at the gastrula stage) differentiate into layers - that will later develop into different tissues and organs - including the mesoderm - ectoderm - and endoderm.






7. The vocal cords are found in the larynx.






8. The phyla of sponges.






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






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






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






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






13. Synthesis






14. Is the outermost of the three main layers of an embryo.






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






16. Includes all living and nonliving components of the Earth to support living things.






17. Disease causing






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






19. 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.






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






21. Is the number of organisms that can be supported within a particular ecosystem.






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






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






24. Anabolism






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






26. Is a phylum that contains sponges.






27. 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.






28. Inorganic phosphate






29. Is the sugar that lactase acts upon.






30. 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.






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






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






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






34. The pharynx is between the nasal passage and the trachea. Air passes into the body via the nasal passage - then passes through the pharynx and on to the trachea.






35. 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).






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






37. 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.






38. What phylum are snakes in?






39. Enzymes are usually __________ to certain reactions.






40. Are easily converted to ATP - but the main energy products of the Krebs cycle liberate electrons then used in the electron transfer reactions.






41. 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).






42. High temperatures






43. 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.






44. Is the process that releases energy for use by the cell.






45. Breaking down






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






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






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






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






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