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. Breaking down






2. The phyla composed of segmented worms.






3. 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.






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






5. Disease causing






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






7. The phyla of sponges.






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






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






10. There was extensive radiation of fish during the Devonian and Silurian periods within the Paleozoic Era.






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






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






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






14. When the water concentration inside and outside the cell is equal - It is said to be in an...






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






16. Is found on the stem between nodes.






17. An enzyme is unaffected by the reactions it catalyzes






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






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






20. Decomposition of living matter for consumption.






21. Is the waxy protective outer coating of leaves.






22. 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.






23. Niche






24. Anabolism






25. Is the major component of sand and is the most abundant element found in the lithosphere. It is not recycled.






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






27. The pituitary gland.






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






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






30. High temperatures






31. Is the outermost layer of cells of the stem.






32. 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.






33. Controls olfactory lobes (smell)






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






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






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






37. The process whereby cells build molecules and store energy (in the form of covalent chemical bonds).






38. Covers and protects the leaf.






39. The transfer of electrons.






40. What phylum are snakes in?






41. In both living and non-living environments.






42. 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






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






44. 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.






45. Refers to the birthrate of a population.






46. Covalent bonds






47. Is made of stacked cells connected by sieve plates that allow nutrients to pass from cell to cell. They transport food made in the leaves (by photosynthesis) to the rest of the plant).






48. Are easily converted to ATP - but the main energy products of the Krebs cycle liberate electrons then used in the electron transfer reactions.






49. Is when expression of genetic traits is determined by weather the trait is inherited from the mother or the father.






50. The phylum of insects (bees).
