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






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






3. Niche






4. Is a coenzyme required in the synthesis of collagen.






5. The individual we recognize as an adult fern.






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






7. Develops from the morula as a thin layer of cells surrounding an internal cavity.






8. 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.






9. Proposes that those individuals within a population that are most adapted to the environment are also the most likely individuals to produce viable offspring.






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






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






12. Protein synthesis






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






14. The pituitary gland.






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






16. Contain one celled eukaryotes such as algae and protozoa.






17. Is the organelle where cellular reproductive processes occur.






18. Is an abundant element found in protoplasm. Together with oxygen - hydrogen - and nitrogen - it composes over 90% of cellular structure.






19. 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






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






21. Breaking down






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






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






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






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






26. Are formed when the plasma membrane of a cell encloses a molecule outside the membrane - then releases a membrane bound sack containing the desired molecule into the cytoplasm. This process allows the cell to absorb molecules that are larger in size






27. Is the sugar that lactase acts upon.






28. Is a kingdom that includes algae and protozoa.






29. Algae and Protozoa belong to the kingdom...






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






31. In DNA Guanine pairs with...






32. Is secreted by the adrenal cortex to promote sodium reabsorption in the kidney.






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






34. The sharp boundary of an ecosystem.






35. Covalent bonds






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






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






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






39. The transfer of electrons.






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






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






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






43. 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






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






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






46. An orienting response to light.






47. Is the waxy protective outer coating of leaves.






48. Is the process that releases energy for use by the cell.






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






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