Quizplus · Accepted Answer

Species C is the only one that contains gene 3, which produces an enzyme that breaks down methane. Methane is a potent greenhouse gas, contributing significantly to global warming. Therefore, studying the enzyme produced by gene 3 in Species C may provide insights into how to slow down global warming by breaking down methane. The functions of the other genes are currently unknown and therefore cannot be used as a basis for selecting a species for this specific study.
