Answer: The correct answer for the fill in the blank is ATP.
ATP ( adenosine triphosphate) is considered as the energy currency of the cell. The energy captured from the food by the living organisms is stored in ATP. It a high energy containing molecule. The energy is stored in its high energy chemical bonds, called as phosphoanhydride bonds ( between phosphate molecules).
Whenever the body requires energy, hydrolysis of ATP takes place ( ATP is converted to ADP and inorganic phos[phate). This results in the release of the stored energy.
Thus, most potential energy captured from food molecules is stored as ATP.
The number of neutrons in each atom
D, low sea levels caused the ice age.
It is b because of all the cells that produce the chemical bond
Adaptation because organisms adapt to avoid extinction.
