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 of breaking down complex materials (foods) to form simpler substances and release energy.






2. Protein synthesis






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






4. Engages in both passive and active transport.






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






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






7. Enzymes are usually __________ to certain reactions.






8. 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.






9. 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.






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






11. 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






12. The phyla of round worms.






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






14. 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.






15. 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






16. Occurs when two populations are geographically isolated from each other. Over time this results in the production of two separate species.






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






18. Subsets below the kingdom level






19. Controls olfactory lobes (smell)






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






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






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






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






24. 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






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






26. Is a substance that changes the speed of a reaction without being affected itself.






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






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






29. A suffix meaning 'to break apart.' O || ||






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






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






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






33. Is the waxy protective outer coating of leaves.






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






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






36. The phyla composed of segmented worms.






37. A sex-linked recessive disorder carried on the x chromosome in which an individual cannot perceive certain colors.






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






39. The vocal cords are found in the larynx.






40. Cleave strands of DNA segments at certain sites.






41. Where protein synthesis occurs. They float unattached in the cytoplasm. They contain RNA that is specific to their function in protein formation.






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






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






44. An orienting response to light.






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






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






47. The number of organisms in a given community - can be above or below the carrying capacity.






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






49. 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.






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