    In order to determine the effect of a certain antibiotic on a species of microorganism, an investigation was carried out. A sample of a specific species of microorganism was added to 100 mL of a liquid culture medium. One mL of a solution of the antibiotic was then added to that culture medium. Each day at 10 a.m., 1 mL of the experimental culture medium was removed and the number of microorganisms in the 1-mL sample was determined. The 1 mL of experimental culture medium was replaced by 1 mL of new sterile culture medium to maintain a constant volume. The results are shown in the table below.

    Base your answers to questions 60 through 63 on the information below and on your knowledge of biology.

    A student wants to bake the biggest loaf of bread in the local baking contest. Each contestant must use the same amounts of flour, sugar, and yeast, but is allowed to vary the type of sugar. Yeast is a microorganism that carries out cellular respiration, which produces carbon dioxide, making the bread rise. The student designs an experiment using the setup below to determine which sugar source (glucose, sucrose, or fructose) will cause the yeast to produce the most carbon dioxide and therefore, the biggest loaf of bread.

    At an observatory in Mauna Loa, Hawaii, scientists have been measuring and collecting data related to changes in the atmosphere since the 1950s. The remote location of the observatory makes it ideal for studying atmospheric conditions that can cause climate change. One specific measurement taken is the amount of atmospheric carbon dioxide. Information for a 7-year period is shown in the graph below.
