Answer: for me the best option is D.
Explanation: lets explain this.
Cellular respiration begins with a process that divides the glucose within the cells making it readily available as a source of energy. This process can occur without oxygen (anaerobic respiration) or in the presence of oxygen (aerobic respiration). Anaerobic respiration generates more excess waste (lactate) than aerobic . Besides, high levels of lactate build within the muscle cells. Excess lactate slows the cellular respiratory process and is experienced as a burning sensation in the muscles if exercise continues.
Answer:

Explanation:
Different species concept are introduced to describe the exact definition and classification of species. Some species concept are biological species contest, morphological species concept and ecological species contest.
According to biological species contest, the group of individual that can breed among themselves and not with the other group. Here, the Drosophila species has been classified by the biologist depending on their mating ability to their group of individual only.
Thus, the answer is biological species contest.
<span>The answer would be C. Diabetes is a metabolic disease
wherein the cells of the body cannot properly respond to insulin or the body
has a low production of insulin. Sometimes, it can be both. Insulin acts as the
balancing hormone for the glucose in the body. Without it, glucose cannot be
