    A)Cells grow during prophase, their DNA replicates during metaphase and separates into two nuclei during anaphase, and the cytoplasm divides during telophase. B)DNA condenses into chromosomes during prophase, chromosomes line up during metaphase and separate during anaphase, and separate nuclei form during telophase. C) Chromosomes replicate during prophase, separate during metaphase and replicate again during anaphase, and nuclei form around the chromosomes during telophase. D) Chromatids separate during prophase, replicate during metaphase and are pulled to opposite ends of the cell during anaphase, and cytokinesis splits the cell in half during telophase.

    Herceptin, a drug developed by the biotechnology industry, is used to treat breast cancer. It is taken only after a patient undergoes a matching diagnostic test. In this way, the drug is only give to those patients who have a certain protein. What is the main benefit of such a technology?

    Less time for development is needed since fewer people get the drug. Costs to the consumers will be greatly reduced. Only those who will benefit receive the drug. Fewer testing requirements will allow the drug to be released sooner.

    In an ecosystem, a wide range of organisms coexist. In a pond ecosystem, one can find amoebae, bacteria, green algae, and fish. Which of the following is the best conclusion one can make regarding the genetic diversity of these organisms?

    A) Green algae will have the greatest genetic diversity because they are photosynthetic and do not depend on other organisms to survive. B)Fish will have the greatest genetic diversity because they receive genetic material from a male and female source. C)Bacteria will have the greatest genetic diversity because their high reproductive rate ensures that some will survive. D)Amoebae will have the greatest genetic diversity because their genetic makeup allows them to survive in many environments.

    A manufacturing company accidentally spills chemicals into a lake bordering their plant. These chemicals are toxic to the phytoplankton living in the lake. Which of the following is the most likely long-term effect if efforts are not made to clean up the spill?

    Large algal blooms will form and toxins in these organisms will kill fish and other wildlife. The phytoplankton will adapt to the new conditions and eventually bring the lake back into equilibrium. Levels of oxygen in the lake will drop and will reduce the lake's ability to support life. Levels of oxygen in the lake will increase as phytoplankton die, and the number of fish will increase.
