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. Are easily converted to ATP - but the main energy products of the Krebs cycle liberate electrons then used in the electron transfer reactions.






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






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






4. Breaking down






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






6. Is the control of protein synthesis. Genetic traits are expressed and specialization of cells occur as a result of the combination of proteins produced by the DNA of a cell.






7. Disease causing






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






9. Is a social behavior of an organism that is beneficial to the group at the individual's expense.






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






11. All store energy within their chemical bonds.






12. 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






13. Inorganic phosphate






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






15. Synthesis






16. Contains optic lobes - controls sight.






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






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






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






20. Allows for the genetic code to be preserved in future generations of cells.






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






22. In DNA Guanine pairs with...






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






24. Is a compound fruit that develops from many ovaries of a single flower fusing together (raspberry).






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






26. Are organic cofactors or coenzymes that are required by some enzymatic reactions.






27. The physical place where a particular organism lives. It must include all the factors that will support its life and reproduction.






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






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






30. Is the earliest period of the Paleozoic era. Began with the Cambrian explosion - this explosion of life resulted in the representatives of most of the modern phyla being present.






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






32. The individual we recognize as an adult fern.






33. The transfer of electrons.






34. Is a substance that changes the speed of a reaction without being affected itself.






35. Developed by the German scientists Schleiden and Schwann - States that all living things are made of cells - cells are the basic units of life - all cells come from pre-existing cells.






36. The vocal cords are found in the larynx.






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






38. 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.






39. 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.






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






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






42. Covalent bonds






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






44. Decomposition of living matter for consumption.






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






46. Layer that will become the gut lining as well as some accessory structures.






47. The bronchi lead to the two lungs where they branch out in all directions into smaller tubules known as bronchioles.






48. Is the waxy protective outer coating of leaves.






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






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