In response to a body temperature above the set point, two effector responses in mammals could be sweating and panting.
Sweating and panting are two processes which are responsible for maintaining thermoregulation in the body. Thermoregulation maintains necessary heat energy in the body. Sweating is a process of removal of water from the body as a result of hot weather conditions. Loss of water occurs from skin. This water when comes in contact of air gives an affect of coolness, hence, keep the body cool in hot climate.
Panting is a process of loss of water in evaporation from the moist lining of the oral cavity and pharynx as a method of temperature regulation in the body.
There is more oxygen and carbon dioxide in the surface of the ocean because these gases rises and floats thus it will stay near the surface. Also, the solubility of these gases in water is small therefore only small concentrations can be found in water.
Mitochondria are needed for energy production, soif you think about it, it makes sense that the muscle cell would have more a muscle cell works far harder than a skin cell hope i helped!!
