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. 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.






2. Super-class of vertebrae including organisms with no jaws.






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






4. Respiratory organs within insects






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






6. An enzyme is unaffected by the reactions it catalyzes






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






8. 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.






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






10. 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.






11. The large brain and upright posture of Homo Sapiens...






12. Most fossils of Hominids are from continents other than...






13. Covalent bonds






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






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






16. Stood upright before there was an increase in brain size.






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






18. 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.






19. 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.






20. 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






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






22. Is an ion that binds to an enzyme making it more able to catalyze a reaction.






23. Is more like branching out of a tree with dead ends and new branches appearing simultaneously than like steps on a ladder.






24. Some enzymes contain a __________ component that is essential to their functions.






25. 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






26. Are more closely related to Homo Sapiens than to other apes - but Homo Sapiens did not evolve from chimpanzees.






27. 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.






28. Include: Vascular tissue - including both xylem and phloem - and sieve plates existing between cells of the stem.






29. Attaches to an enzyme and blocks the enzyme reaction rather than enhancing it - like a prosthetic group would.






30. Controls balance and muscle coordination






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






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






33. Are tubes constructed of a geometrical arrangement of microtubules in a pinwheel shape. Their function includes the formation of new microtubules - but is primarily to form the structural skeleton around which cells split during mitosis and meiosis.






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






35. An orienting response to light.






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






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






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






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






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






41. 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.






42. The vocal cords are found in the larynx.






43. 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.






44. The phyla composed of segmented worms.






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






46. Is the sugar that lactase acts upon.






47. Transfers water and does not require sieve plates to allow nutrients through.






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






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






50. 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.
