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. Enzymes are usually __________ to certain reactions.






2. The phyla of round worms.






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






4. 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.






5. The phyla composed of segmented worms.






6. Carbon - nitrogen - phosphorous - and water. These are all recycled through biogeochemical processes.






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






8. 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.






9. Digestive enzymes - hydrochloric acid - and gastric juices which aid in digestion. The mucous secreted by the stomach protects the stomach lining from the acids and juices.






10. Contains optic lobes - controls sight.






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






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






13. 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.






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






15. 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






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






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






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






19. Niche






20. 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.






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






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






23. Mitochondria - they constitute the center of cellular respiration.

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






25. Protein synthesis






26. Controls balance and muscle coordination






27. Covalent bonds






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






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






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






32. A reaction that adds water to another compound. (2 hydrogens - 1 oxygen).






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






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






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






36. States that where random mating is occurring within a population that is in equilibrium with its environment - the gene frequencies and genotype ratios will remain constant from generation to generation. It is a mathematical formula that shows why re






37. Is the sugar that lactase acts upon.






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






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






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






41. 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.






42. Include: Vascular tissue - including both xylem and phloem - and sieve plates existing between cells of the stem.






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






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






45. 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.






46. Is more like branching out of a tree with dead ends and new branches appearing simultaneously than like steps on a ladder.






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






48. What phylum are snakes in?






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






50. Is composed of an anterior and posterior lobe. The stalk of the lobe is connected to the hypothalamus. Antidiuretic Hormone (AH) is produced in the hypothalamus and stored in the posterior pituitary. Upon nervous stimulation from the hypothalamus - t
