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. Subsets below the kingdom level






2. Is a kingdom that includes algae and protozoa.






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






4. Has extreme cold temperatures - low precipitation - modified grassland - perma-frost - a short growing season and some plants and animals.






5. The role played by an organism in its food chain.






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






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






8. Engages in both passive and active transport.






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






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






11. Plants and animals obtain usable nitrogen






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






13. Controls balance and muscle coordination






14. What phylum are snakes in?






15. Fossilized burrows from multicellular organisms begin to appear in the geological record approximately 700 million years ago during the Precambrian period. These multicellular animals had only soft parts and could not be fossilized.






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






17. Are formed when the plasma membrane of a cell encloses a molecule outside the membrane - then releases a membrane bound sack containing the desired molecule into the cytoplasm. This process allows the cell to absorb molecules that are larger in size






18. The phyla composed of segmented worms.






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. The transfer of electrons.






21. Some energy is lost as heat and becomes unusable.






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






23. Is weaker than ionic - covalent - disulfide - or double bonds.






24. 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.






25. Is found on the stem between nodes.






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






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






28. 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.






29. The phylum of insects (bees).






30. The vocal cords are found in the larynx.






31. The trachea includes the windpipe or larynx in its upper portion - and the glottis - an opening that allows the gases to pass into the two branches known as the bronchi.






32. An orienting response to light.






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






34. 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).






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






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






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






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






39. 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






40. Is a special protein that acts as a catalyst for organic reactions.






41. Is the organelle where cellular reproductive processes occur.






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






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






44. 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






45. Produces the most ATP molecules - yielding 34 ATPs per glucose molecule.






46. Veins in the leaf and are also distributed throughout the stem






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. 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






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






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