Which of the following statements best compares nuclear power and hydropower based on their rates of renewal?
A. Hydropower has a faster rate because water is continuously being recycled through the hydrogeological cycle.
B. Nuclear power has a faster rate because all elements are spontaneously radioactive and are a source of nuclear energy.
C. Hydropower has a slower rate because a large volume of water vapor that evaporates takes several years to return to water cycle.
D. Nuclear power has a slower rate because the nuclear waste produced is not radioactive and thus cannot be used further as a fuel.

Consider a culture medium on which only gram-positive organisms such as staphylococcus aureus colonies can grow due to an elevated nacl level. a yellow halo surrounds the growth, indicating the bacterium fermented a sugar in the medium, decreasing the ph as a result and changing the color of a ph indicator chemical. this type of medium would be referred to as a differential and enrichment culture.
