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






2. 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.






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






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






5. Disease causing






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






7. 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.






8. 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






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






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






11. Protein synthesis






12. An enzyme is unaffected by the reactions it catalyzes






13. 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.






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






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






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






17. Controls olfactory lobes (smell)






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






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






20. Is a kingdom that includes algae and protozoa.






21. The phyla of sponges.






22. The physical place where a particular organism lives. It must include all the factors that will support its life and reproduction.






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






24. 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






25. 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.






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






27. The sharp boundary of an ecosystem.






28. Produce antibodies into the bloodstream that find and attach themselves to foreign antigens (toxins - bacteria).






29. 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.






30. The individual we recognize as an adult fern.






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






32. Is secreted by the adrenal cortex to promote sodium reabsorption in the kidney.






33. 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.






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






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






36. There was extensive radiation of fish during the Devonian and Silurian periods within the Paleozoic Era.






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. High temperatures






39. All store energy within their chemical bonds.






40. Internally generated patterns of body functions - including hormonal signals - sleep - blood pressure - and temperature regulation - which have approximately a 24-hour cycle and occur even in the absence of normal cues about whether it is day or nigh






41. Inorganic phosphate






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






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






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






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






46. The role played by an organism in its food chain.






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






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






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






50. Is a phylum that contains sponges.
