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. Contains optic lobes - controls sight.






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






3. High temperatures






4. The transfer of electrons.






5. Plants and animals obtain usable nitrogen






6. In DNA Thymine pairs with...






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






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






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






10. Produce seeds without flowers. They include conifers (cone-bearers) and cycads.






11. Anabolism






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






13. 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






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






15. 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.






16. Is the major component of sand and is the most abundant element found in the lithosphere. It is not recycled.






17. Is the sugar that lactase acts upon.






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






19. The vocal cords are found in the larynx.






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






21. Between the endoderm and ectoderm - layer that will eventually form the muscles - and organs of the skeletal - circulatory - respiratory - reproductive - and excretory systems.






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






23. 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.






24. 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.






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






26. 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.






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






28. 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






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






30. 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.






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






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






33. Is the waxy protective outer coating of leaves.






34. 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.






35. 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






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






37. 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.






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






39. Ended with the extinction of the dinosaurs.






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






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






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






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






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






45. 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.






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






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. Decomposition of living matter for consumption.






49. Respiratory organs within insects






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