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. 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.






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






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






5. What phylum are snakes in?






6. Controls sensory and motor responses - and controls memory - speech - and intelligence factors.






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






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






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






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






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






12. Are tubes constructed of a geometrical arrangement of microtubules in a pinwheel shape. Their function includes the formation of new microtubules - but is primarily to form the structural skeleton around which cells split during mitosis and meiosis.






13. In order to become an established part of an island ecosystem there must be a populations large enough to ensure _________ - a food source - a suitable habitat - and a source of moisture.






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






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






16. The phyla of sponges.






17. A cell will only remain stable if the surface area of the plasma membrane maintains a __________ with the volume of the cytoplasm.






18. The cells of a developing embryo (at the gastrula stage) differentiate into layers - that will later develop into different tissues and organs - including the mesoderm - ectoderm - and endoderm.






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






20. Is a compound fruit that forms from several ovaries of separate flowers that fuse together during ripening (strawberry - or pineapple).






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






22. 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






23. The class composed of birds.






24. Absorb a photon of light and is found in the grana of the chloroplast.






25. The phyla composed of segmented worms.






26. Cleave strands of DNA segments at certain sites.






27. Anabolism






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






29. Controls balance and muscle coordination






30. 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






31. Disease causing






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






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






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






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






36. An opportunistic life strategy strategy. Lichens invading a bare rock area after a volcanic eruption is an example.






37. 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).






38. An enzyme is unaffected by the reactions it catalyzes






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






40. 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).






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






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






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






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






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






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






47. Covers and protects the leaf.






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






49. Proposes that those individuals within a population that are most adapted to the environment are also the most likely individuals to produce viable offspring.






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