In parasitic insects such as lice, the melanism is an evolutionary strategy of adaptive significance
Explanation:
In lice, different body colors represent an adaptive advantage because this feature should enable them to host on different hair colors and be undetected by the host. Therefore, different colors confer to this species the capacity to survive in different types of environments (i.e., hair colors)
If there is no oxygen , the cells go through anaerobic respiration which leads tot he build of lactic acid in the muscles. This is why we get sore and feel the burn during a workout.
