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. 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.






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






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






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






5. 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.






6. Is a coenzyme required in the synthesis of collagen.






7. The part of the earth that contains all living things - including the atmosphere (air) - the lithosphere (earth) - and the hydrosphere (water).






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






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






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






11. 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.






12. Controls hunger and thirst






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






14. 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






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






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






17. Is the waxy protective outer coating of leaves.






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






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






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






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






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






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






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






25. Is found on the stem between nodes.






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






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






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






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






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






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






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






33. 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.






34. The physical place where a particular organism lives. It must include all the factors that will support its life and reproduction.






35. 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.






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






37. 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).






38. 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






39. All store energy within their chemical bonds.






40. Covers and protects the leaf.






41. Can be accounted for by the theory of punctuated equilibrium. The fossil record shows periods of stability with regard to appearance and disappearance of species as well as periods of sudden change.






42. The individual we recognize as an adult fern.






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






44. An enzyme is unaffected by the reactions it catalyzes






45. 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.






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






47. The class composed of birds.






48. Develops from the morula as a thin layer of cells surrounding an internal cavity.






49. 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.






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