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 the process that releases energy for use by the cell.






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






3. Occurs when an individual learns not to respond to a particular stimulus - for instance when a stimulus is repeated many times without consequence.






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






5. Includes all living and nonliving components of the Earth to support living things.






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






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






8. Covalent bonds






9. Most fossils of Hominids are from continents other than...






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






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






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






13. Contains the chromosomes and is the site of reproduction through mitosis and meiosis.






14. Is the outermost of the three main layers of an embryo.






15. 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






16. The preservation of the integrity of genetic information from one generation to another.






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






18. Carbon - Hydrogen - Oxygen - and Nitrogen






19. Most chemical pollutants accidentally ingested by humans are __________ - mixed with broken down pigments in the bile - then bile is secreted into the small intestine - proceeds to the large intestine - and is expelled in the feces.






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


21. Plants and animals obtain usable nitrogen






22. The phyla composed of segmented worms.






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






25. Controls balance and muscle coordination






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






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






28. Is an ion that binds to an enzyme making it more able to catalyze a reaction.






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






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






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






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






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






34. 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.






35. A type of innate behavior (instinct.) The FAP is a preprogrammed response to a particular stimulus (known as a releaser stimulus). FAP's include courtship behaviors and feeding of young. These are not learned behaviors - they are automatically perfor






36. Sex-linked recessive disorder carried on the x chromosome defined by the absence of one or more proteins required for blood clotting






37. Becomes available for erosion as undersea sedimentary rocks are up-thrust by volcanic activity - erosion releases it from rocks into streams where it combines with oxygen to form phosphates in lakes that are then absorbed by plants - it is recycled t






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






39. Enzymes are usually __________ to certain reactions.






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






41. In DNA Guanine pairs with...






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






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






44. The phyla of sponges.






45. In both living and non-living environments.






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






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






48. Channels is cell membranes that carry water between cells.






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






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