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. Where protein synthesis occurs. They float unattached in the cytoplasm. They contain RNA that is specific to their function in protein formation.






2. 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






3. Inorganic phosphate






4. Is very rare and is not absorbed by plant leaves. Phosphorous is nearly always found in solid form.






5. Anabolism






6. Produce adrenaline. This hormone is a well-known constrictor of blood vessels.






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






8. Contains optic lobes - controls sight.






9. Is the sugar that lactase acts upon.






10. What phylum are snakes in?






11. Contain organisms that are multicellular eukaryotes including vertebrates and invertebrates.






12. Is a social behavior of an organism that is beneficial to the group at the individual's expense.






13. Consists of undifferentiated cells capable of quick growth and specialization. It is responsible for elongation of the stem.






14. The vocal cords are found in the larynx.






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






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






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






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






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






20. Process in which elements - chemical compounds - and other forms of matter are passed from one organism to another and from one part of the biosphere to another.






21. 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.






22. An orienting response to light.






23. Protein synthesis






24. Controls olfactory lobes (smell)






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






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






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






28. 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






29. Occurs when an individual learns not to respond to a particular stimulus - for instance when a stimulus is repeated many times without consequence.






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






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






32. Secretes insulin to lower blood sugar and maintain equilibrium. A person eats three candy bars. Within minutes this endocrine gland affects blood-glucose homeostasis.






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






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






35. Fruits that develop from a single ripened ovary (apple - olive - acorn - cucumber).






36. Are the organelles where cellular respiration occurs.






37. Is the outermost of the three main layers of an embryo.






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






39. Is a special protein that acts as a catalyst for organic reactions.






40. 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.






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






42. 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.






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






44. Controls hunger and thirst






45. Synthesis






46. The lineage that led to the modern Homo Sapiens diverged from the lineage that led to the modern chimpanzee.






47. 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.






48. 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






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






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