Methanotrophs affect global temperature. This is because:
A. Methanotrophs metabolize methane, thereby reducing the amount of methane in the atmosphere. Since methane is one of the greenhouse gases whose accumulation causes a rise in global temperature, its reduction by methanotrophs helps prevent global warming.
B. Methanotrophs convert methane to carbon dioxide and increase the amount of carbon dioxide in the atmosphere. Since carbon dioxide is one of the greenhouse gases whose accumulation causes a rise in global temperature, its production by methanotrophs contributes to global warming.
C. Methanotrophs convert carbon dioxide to methane and increase the amount of methane in the atmosphere. Since methane is one of the greenhouse gases whose accumulation causes a rise in global temperature, its production by methanotrophs contributes to global warming.
D. Methanotrophs convert methane to carbon dioxide, thereby decreasing the amount of methane in the environment but increasing the amount of carbon dioxide there. Since both methane and carbon dioxide are greenhouse gases whose accumulation causes a rise in global temperature, the decrease in one cancels the increase in the other and methanotrophs have no net effect on global warming.
E. Methanotrophs combine carbon dioxide and methane to form petroleum and in this way take both methane and carbon dioxide out of the atmosphere. Since both methane and carbon dioxide are greenhouse gases whose accumulation causes a rise in global temperature, the decrease in both helps prevent global warming.

Short tandem repeats (STRs) are highly variable sets of repeating sequences within the genome. Because the probability of any two having an identical number of repeats at different STR regions within the genome is astronomically low, they are useful for identifying samples of DNA. With so much variability in these regions of DNA, one would assume that STRs:
A) occur outside of protein-coding regions of DNA. B) are responsible for the physical and biochemical variation among individuals. C) are introns. D) are not inherited the same way as other genes. E) are always homozygous
During spring time in Maine, male moose often enter a cow pasture and begin calling to the female cows. The moose may even try to mount the female but the male genitalia do not fit properly inside the female genitalia. This is an example of
A. habitat isolation. B. gametic isolation. C. mechanical isolation. D. behavioral isolation. E. temporal isolation.
