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. 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.






2. Contain organisms that are multicellular eukaryotes including vertebrates and invertebrates.






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






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






5. 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.






6. Approximately 7 - making it neither basic (under 7) nor alkaline (over 7).






7. 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.






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






9. Is a protein - which is a polymer of amino acids. They generally have the suffix -ase- like lactase.






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






11. 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






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






13. Disease causing






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






15. Is a molecule that stores information for protein synthesis and genetic coding.






16. The sharp boundary of an ecosystem.






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






18. Are more closely related to Homo Sapiens than to other apes - but Homo Sapiens did not evolve from chimpanzees.






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






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






21. In DNA Thymine pairs with...






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






23. 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.






24. Anabolism






25. 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.






26. 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






27. The most recent and present era. It includes the radiation of flowering plants - the angiosperms.






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






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






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






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






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






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






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






35. Fruits that develop from a single ripened ovary (apple - olive - acorn - cucumber).






36. Are surrounded by capillaries that allow for carbon dioxide to diffuse into the lungs and oxygen to diffuse out.






37. A length of DNA (with corresponding histones) is responsible for the production of a certain protein that causes a particular trait to be expressed in an organism.






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






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






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






41. The individual we recognize as an adult fern.






42. The phyla composed of segmented worms.






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






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






45. 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).






46. Chlorophyll pigments absorb photons of light - leaving the chlorophyll in a higher energy (excited) state - these then supply energy to reactions that produce ATP from ADP and Pi.






47. 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.






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






49. Is a kind of plain characterized by a warm climate - grassland - and seasonally dry climate conditions.






50. An enzyme is unaffected by the reactions it catalyzes
