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. 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.






2. Is comprised of all the organisms that interact within a given ecosystem whether or not it is at carrying capacity.






3. 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.






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






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

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






8. Is a phylum that contains sponges.






9. The phyla composed of segmented worms.






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






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






12. 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

14. The class composed of birds.






15. Is composed of an anterior and posterior lobe. The stalk of the lobe is connected to the hypothalamus. Antidiuretic Hormone (AH) is produced in the hypothalamus and stored in the posterior pituitary. Upon nervous stimulation from the hypothalamus - t






16. Energy transformations that occur as chemicals are broken down or synthesized within the cell.






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






18. The pituitary gland.






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

26. The phylum of insects (bees).






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






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






29. Bacteria break ammonia into nitrites - then into nitrates that are usable by plants; volcanic activity produces ammonia and nitrates that enter the soil and can be absorbed by plants; lightning reacts with atmospheric nitrogen to form nitrates that a

35. 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.






36. Has an equal (50%) chance of being passed from a carrier mother to a son or a daughter.






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