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






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






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






4. Is a kingdom that includes algae and protozoa.






5. The class composed of birds.






6. Approximately 7 - making it neither basic (under 7) nor alkaline (over 7).






7. Synthesis






8. The phyla composed of segmented worms.






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






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






11. Enzymes are usually __________ to certain reactions.






12. Is found in the root cap and is responsible for quick growth in the roots.






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






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






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






16. Anabolism






17. Mass extinctions promote diversification because _______________ - making conditions favorable for the establishment of new - diverse species.






18. Sex-linked recessive disorder carried on the x chromosome defined by the absence of one or more proteins required for blood clotting






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






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






21. Decomposition of living matter for consumption.






22. 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






23. The phyla of round worms.






24. Some energy is lost as heat and becomes unusable.






25. The transfer of electrons.






26. High temperatures






27. Are the organelles where cellular respiration occurs.






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






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






30. Controls hunger and thirst






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






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






33. Respiratory organs within insects






34. 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.






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






36. The number of organisms in a given community - can be above or below the carrying capacity.






37. Engages in both passive and active transport.






38. Controls balance and muscle coordination






39. Contains many genes and is a structure comprised of linear DNA and associated proteins.






40. Covers and protects the leaf.






41. Nonvascular plants such as mosses which lack tissue for conducting food or water.






42. 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.






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. Can be accounted for by the theory of punctuated equilibrium. The fossil record shows periods of stability with regard to appearance and disappearance of species as well as periods of sudden change.






45. The pituitary gland.






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






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






48. What phylum are snakes in?






49. Is the organelle where cellular reproductive processes occur.






50. Has extreme cold temperatures - low precipitation - modified grassland - perma-frost - a short growing season and some plants and animals.
