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. Contains multicellular photosynthetic eukaryotic organisms including gymnosperms and angiosperms.






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






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






4. Engages in both passive and active transport.






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






6. The process of forming eggs and sperm cells in the reproductive organs.






7. Some patrol the blood for antigens - but are also equipped to destroy antigens. They may regulate immune responses as well.






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






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






10. Is a molecule that stores information for protein synthesis and genetic coding.






11. The role played by an organism in its food chain.






12. Must be present for photosynthesis to occur - it is not used up in the process.






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






15. Is found on the stem between nodes.






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






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






18. 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.






19. 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






20. (of some plants or fungi) feeding on dead or decaying organic matter






21. Is a behavior that is learned during a critical point (often very early) in an individual's life. Imprinting enables the young the recognize members of their own species.






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






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






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






25. Is the sugar that lactase acts upon.






26. Biotic (living) factors such as population and food source - and abiotic (non-living) factors such as weather - temperature - soil features - sunlight).






27. The class composed of birds.






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






29. The cells of a developing embryo (at the gastrula stage) differentiate into layers - that will later develop into different tissues and organs - including the mesoderm - ectoderm - and endoderm.






30. 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.






31. Process of breaking down complex materials (foods) to form simpler substances and release energy.






32. Is the waxy protective outer coating of leaves.






33. The phyla composed of segmented worms.






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






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






36. 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.






37. The process whereby cells build molecules and store energy (in the form of covalent chemical bonds).






38. Is disorganized - unravelled - DNA with histones attached.






39. Is a kingdom that includes algae and protozoa.






40. Covalent bonds






41. What phylum are snakes in?






42. Controls hunger and thirst






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






44. In both living and non-living environments.






45. Transfers water and does not require sieve plates to allow nutrients through.






46. Provide rigidity to plant cells (and some bacteria) and are not found within animal cells.






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






48. Is the outermost layer of cells of the stem.






49. Breaking down






50. 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
