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. Niche






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






3. Is a behavior that is learned during a critical point (often very early) in an individual's life. Imprinting enables the young the recognize members of their own species.






4. The effect of a substrate concentration on the initial reaction rate in the presence of a limited amount of enzyme: _________________ as the concentration of substrate is increased until all the enzymes are used - then the reaction rate will level of






5. 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.






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






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






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






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






10. 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.






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






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






13. 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.






14. Is secreted by the adrenal cortex to promote sodium reabsorption in the kidney.






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






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






17. Transparency - polarity - high specific heat - and density (lower density when solid than when liquid.).






18. Is more like branching out of a tree with dead ends and new branches appearing simultaneously than like steps on a ladder.






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






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






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






22. Decomposition of living matter for consumption.






23. Contain one celled eukaryotes such as algae and protozoa.






24. Layer that will become the gut lining as well as some accessory structures.






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






26. Anabolism






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






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






29. Developed by the German scientists Schleiden and Schwann - States that all living things are made of cells - cells are the basic units of life - all cells come from pre-existing cells.






30. 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.






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






32. Breaking down






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






34. 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.






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






36. What phylum are snakes in?






37. Super-class of vertebrae including organisms with jaws.






38. Is an accidental change of the DNA sequence of the gene that can result in creating a change of trait that is not found in the parent.






39. Are the monomers that form nucleic acids - containing a sugar - phosphate group - and a nitrogenous base.






40. Super-class of vertebrae including organisms with no jaws.






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






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






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






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






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






46. Disease causing






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






48. Is a phylum that contains sponges.






49. Synthesis






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