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






2. Absorb a photon of light and is found in the grana of the chloroplast.






3. 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.






4. Ended with the extinction of the dinosaurs.






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






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






7. Respiratory organs within insects






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






9. Occurs when an individual from an adjacent population of the same species immigrates and breeds with a member of a previously locally isolated group - resulting in a change in the gene pool.






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






11. Protein synthesis






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






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






14. The large brain and upright posture of Homo Sapiens...






15. Is the waxy protective outer coating of leaves.






16. Layer that will become the skin - some endocrine glands - and the nervous system.






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






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






19. The systematic search for individuals with a specific genotype in a delineated population.






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






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






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






23. 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.






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






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






26. Is a disease caused by lack of vitamin C in which the body is unable to build enough collagen (a major component of connective tissue).






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






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






29. Controls olfactory lobes (smell)






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






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






32. In DNA Guanine pairs with...






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






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






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






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






37. Is a phylum that contains jellyfish - hydra - etc.






38. Disease causing






39. Stood upright before there was an increase in brain size.






40. Are tubes constructed of a geometrical arrangement of microtubules in a pinwheel shape. Their function includes the formation of new microtubules - but is primarily to form the structural skeleton around which cells split during mitosis and meiosis.






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






42. Anabolism






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






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






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






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






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






48. The solid mass of cells resulting from the cleavage of the ovum before the formation of a blastula.






49. The phylum of insects (bees).






50. Is composed of a double layer (bilayer) of phospholipids with protein globules imbedded within the layers. The construction of the membrane allows it to aid the function of the cell by permitting entrance and exit of molecules as needed by the cell.
