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. Produce adrenaline. This hormone is a well-known constrictor of blood vessels.






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






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






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






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






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






7. Enzymes are usually __________ to certain reactions.






8. Is a kind of plain characterized by a warm climate - grassland - and seasonally dry climate conditions.






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






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






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






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






13. The size of a cell is limited by the ratio of its surface area to volume.






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






15. Breaking down






16. 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.






17. Ended with the extinction of the dinosaurs.






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






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






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






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






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






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






24. The phyla of round worms.






25. 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.






26. The phyla composed of segmented worms.






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






28. Some enzymes contain a __________ component that is essential to their functions.






29. Algae and Protozoa belong to the kingdom...






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






31. 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






32. 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






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






34. Is a compound fruit that develops from many ovaries of a single flower fusing together (raspberry).

36. Covers and protects the leaf.






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






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






39. The class composed of birds.






40. May be ions or non-protein molecules - they are similar to cofactors - but differ in that they are tightly attached by covalent bonds to the enzyme - rather than being separate atoms or molecules.






41. Protein synthesis






42. Cleave strands of DNA segments at certain sites.






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






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






45. Bacteria break ammonia into nitrites - then into nitrates that are usable by plants; volcanic activity produces ammonia and nitrates that enter the soil and can be absorbed by plants; lightning reacts with atmospheric nitrogen to form nitrates that a






46. Is the period when the cell is active in carrying on the function it was designed to perform within the organism. Cells spend much more time in interphase than in cell division.
