I think the correct answer would be the third option. It is the increased body temperature that is not a natural function of water in the body. It does not function to increase temperature but to regulate the temperature of the body. Also, it is an important molecule for the reactions in the body to occur.
The function of ATP IN living organisms is that ATP is stored in all the cells for energy of all cells.
ATP captures the chemical energy by digesting food particles, breaking it down to deliver into the
cell process enough to disperse ATP throughout the bloodstream for energy to every cell of the body, to work properly in digestion, releases it to fuel all cells in the body, this is the last process for fuel in the cell system in the digestive process..
For example, insects use wings to fly like bats and birds, but the wing structure and embryonic origin is completely different. These are called analogous structures... Some structures are both analogous and homologous: the wings of a bird and the wings of a bat are both homologous and analogous.
Hope that helped!!
