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






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






3. Are the organelles where cellular respiration occurs.






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






5. 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






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






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






8. 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.






9. 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






10. Cleave strands of DNA segments at certain sites.






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






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






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






14. Is a kingdom that includes algae and protozoa.






15. Refers to the birthrate of a population.






16. Niche






17. Is found on the stem between nodes.






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






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






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






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






22. The systematic search for individuals with a specific genotype in a delineated population.






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






24. The large brain and upright posture of Homo Sapiens...






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






26. A reaction that adds water to another compound. (2 hydrogens - 1 oxygen).






27. The sharp boundary of an ecosystem.






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






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






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






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






32. Engages in both passive and active transport.






33. In both living and non-living environments.






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






35. Has extreme hot or cold temperatures - with very low precipitation - sandy or rocky terrain - sparse vegetation (mainly succulents) - small animals - rodents - and reptiles.






36. Is the waxy protective outer coating of leaves.






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






38. Is the control of protein synthesis. Genetic traits are expressed and specialization of cells occur as a result of the combination of proteins produced by the DNA of a cell.






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






40. The pharynx is between the nasal passage and the trachea. Air passes into the body via the nasal passage - then passes through the pharynx and on to the trachea.






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






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






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






44. Controls hunger and thirst






45. Respiratory organs within insects






46. An orienting response to light.






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






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






49. 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






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