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.

3. Is a kingdom that includes algae and protozoa.






4. Decomposition of living matter for consumption.






5. 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






6. All store energy within their chemical bonds.






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






8. 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

13. An orienting response to light.






14. Controls olfactory lobes (smell)






15. The effect of a substrate concentration on the initial reaction rate in the presence of a limited amount of enzyme: _________________ as the concentration of substrate is increased until all the enzymes are used - then the reaction rate will level of






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






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

24. 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.






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