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






2. 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.






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






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






5. Is an accidental change of the DNA sequence of the gene that can result in creating a change of trait that is not found in the parent.






6. Protein synthesis






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






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






9. Covers and protects the leaf.






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






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






12. 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.






13. 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






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






15. In both living and non-living environments.






16. Controls balance and muscle coordination






17. Subsets below the kingdom level






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






19. Are where the sugars synthesized by photosynthesis travel through to various parts of the plant.






20. Is found on the stem between nodes.






21. Refers to the birthrate of a population.






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






23. Is the sugar that lactase acts upon.






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






25. 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.






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






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






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






29. The destruction of gametes - (sex cells such as sperm and eggs).






30. An enzyme is unaffected by the reactions it catalyzes






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






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






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






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






35. Internally generated patterns of body functions - including hormonal signals - sleep - blood pressure - and temperature regulation - which have approximately a 24-hour cycle and occur even in the absence of normal cues about whether it is day or nigh






36. Controls sensory and motor responses - and controls memory - speech - and intelligence factors.






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






38. The vocal cords are found in the larynx.






39. Is a kingdom that includes algae and protozoa.






40. A hydrogen bond involves the ________________ and can be easily broken.






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






42. 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






43. Carbon - Hydrogen - Oxygen - and Nitrogen






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






45. Small - green - heart-shaped gametophyte plant form of a fern that can make its own food and absorb water and nutrients from the soil






46. All store energy within their chemical bonds.






47. 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.






48. Is the organelle where cellular reproductive processes occur.






49. 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






50. Contains organisms that are multicellular eukaryotes including molds and mushrooms.
