Answer:
The relative frequency of the mutation will increase as time passes.
Explanation:
This random mutation has, by chance, caused a phenotype that is beneficial to the bacteria. This mutation improves the fitness of the bacteria, as they are able to utilize more food sources. This reduces the chance of starvation and death of the cell. Therefore, cells with this mutation are more likely to survive, and for longer.
In times where nutrients are scarce, bacteria without the population will die off. But the bacteria with this mutation will be more likely to survive and pass on their genetic material. Therefore, over time, the frequency of this mutation will increase.

GMO benefits the environment (:
Aristotle based his classification system off of observations of animals, and used physical characteristics to divide animals into two groups
Answer:
D. Clostridium does not have enzymes to process toxic oxygen
Explanation:
Obligate anaerobes are microorganisms killed by normal atmospheric concentrations of oxygen (20.95% O2). Oxygen tolerance varies between species, some capable of surviving in up to 8% oxygen, others losing viability unless the oxygen concentration is less than 0.5%. in other words, Obligate anaerobes are organism which can only live in environments which lack oxygen. Unlike the majority of organisms in the world, these organisms are poisoned by oxygen.
Therefore clostridium do not have enzymes to process this oxygen which is toxic for it
