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.
You can say it as "Constituent Particles" in another term..
The appropriate response is hydrogen bonds. Fever is an adjust of gainful and destructive impacts. High fevers can have a tendency to skew the adjust toward the destructive.
The reality of the matter is that protein optional structure (generally hydrogen bonds) start to denature when moving toward 41 degC (106 degF), however energy likewise change. Energy is a quite major ordeal, even a little temperature move can altogether affect the speed of a response or connection.
It wants you to explain why its a chemical change. Signs of chemical changes are formation of gas bubbles, cloudyness, change in color or odor.
