B because the higher the temperature of air, the faster the molecules move, as the air is heated up, the air molecules move faster, which when the temperature is higher, the air molecules are less dense
Regulates body temperature (sweating, shivering), blood pressure, pH levels, and glucose (sugar) levels
Hind leg length will increase so speed will increase
