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 the organelle where cellular reproductive processes occur.






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






3. The transfer of electrons.






4. 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






5. 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.






6. Anabolism






7. Is found on the stem between nodes.






8. The destruction of gametes - (sex cells such as sperm and eggs).






9. Is a kingdom that includes algae and protozoa.






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






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






12. 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).






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






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






15. 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.






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






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






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






19. In DNA Thymine pairs with...






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






22. 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.






23. Small - green - heart-shaped gametophyte plant form of a fern that can make its own food and absorb water and nutrients from the soil






24. A sex-linked recessive disorder carried on the x chromosome in which an individual cannot perceive certain colors.






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






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






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. High temperatures






29. Is the earliest period of the Paleozoic era. Began with the Cambrian explosion - this explosion of life resulted in the representatives of most of the modern phyla being present.






30. Decomposition of living matter for consumption.






31. Subsets below the kingdom level






32. 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.






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






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






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






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






37. 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.






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






39. 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.






40. Disease causing






41. Provide rigidity to plant cells (and some bacteria) and are not found within animal cells.






42. The phyla of sponges.






43. 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.






44. Is the sugar that lactase acts upon.






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






46. 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.






47. The part of the earth that contains all living things - including the atmosphere (air) - the lithosphere (earth) - and the hydrosphere (water).






48. Super-class of vertebrae including organisms with jaws.






49. 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.






50. Some energy is lost as heat and becomes unusable.
