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






2. Is a phylum that contains sponges.






3. Is a compound fruit that develops from many ovaries of a single flower fusing together (raspberry).






4. Breaking down






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






6. A reaction that adds water to another compound. (2 hydrogens - 1 oxygen).






7. 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.






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






9. Carbon - Hydrogen - Oxygen - and Nitrogen






10. 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.






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






12. Are surrounded by capillaries that allow for carbon dioxide to diffuse into the lungs and oxygen to diffuse out.






13. Engages in both passive and active transport.






14. 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.






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






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






17. The phylum of insects (bees).






18. A cell will only remain stable if the surface area of the plasma membrane maintains a __________ with the volume of the cytoplasm.






19. 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.






20. 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.






21. The phyla of round worms.






22. Are organic cofactors or coenzymes that are required by some enzymatic reactions.






23. A type of innate behavior (instinct.) The FAP is a preprogrammed response to a particular stimulus (known as a releaser stimulus). FAP's include courtship behaviors and feeding of young. These are not learned behaviors - they are automatically perfor






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






25. 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.






26. Controls balance and muscle coordination






27. Is the organelle where cellular reproductive processes occur.






28. In DNA Thymine pairs with...






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






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






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






32. Contains organisms that are multicellular eukaryotes including molds and mushrooms.






33. Is the sugar that lactase acts upon.






34. Anabolism






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






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






37. 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.






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






39. Enzymes are usually __________ to certain reactions.






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






41. 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.






42. The class composed of birds.






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






44. The transfer of electrons.






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






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






47. 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.






48. When stems bend toward the light it is due to _____________ the hormone auxin - in response to light - migrates from the light to the dark side of the shoot tip. The cells on the dark side now contain more auxin - which causes the cells on that side






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






50. Protein synthesis
