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. Synthesis






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






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






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






5. Is the sugar that lactase acts upon.






6. In DNA Guanine pairs with...






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






8. Some enzymes contain a __________ component that is essential to their functions.






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






10. Is weaker than ionic - covalent - disulfide - or double bonds.






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






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






13. High temperatures






14. The class composed of birds.






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






16. Cleave strands of DNA segments at certain sites.






17. 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.






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






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






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






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






22. 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.






23. The trachea includes the windpipe or larynx in its upper portion - and the glottis - an opening that allows the gases to pass into the two branches known as the bronchi.






24. A sex-linked recessive disorder carried on the x chromosome in which an individual cannot perceive certain colors.






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






26. Inorganic phosphate






27. Covalent bonds






28. Most fossils of Hominids are from continents other than...






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. Plants that produce flowers as reproductive organs. They have two divisions - monocots and dicots.






31. The phyla of sponges.






32. Produces the most ATP molecules - yielding 34 ATPs per glucose molecule.






33. The size of a cell is limited by the ratio of its surface area to volume.






34. Has extreme hot or cold temperatures - with very low precipitation - sandy or rocky terrain - sparse vegetation (mainly succulents) - small animals - rodents - and reptiles.






35. 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.






36. 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.






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






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






39. 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.






40. Super-class of vertebrae including organisms with jaws.






41. Enzymes are usually __________ to certain reactions.






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






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






44. The phyla composed of segmented worms.






45. Is an accidental change of the DNA sequence of the gene that can result in creating a change of trait that is not found in the parent.






46. Is the period when the cell is active in carrying on the function it was designed to perform within the organism. Cells spend much more time in interphase than in cell division.






47. Anabolism






48. Is the organelle where cellular reproductive processes occur.






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






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