The answer is 3
Explanation:
To answer the question that is: "which factors affect a river's load", we have to understand that all the things mentioned are important. All these options (river's slope, streambed shape and volume of flow) affect the amount of energy that the river has to spend and the way the river spend that energy, so, it is right to mark the alternative d) all of the above.
Answer;
-The above statement is True.
ATP is an unstable, high-energy molecule that provides body cells with a form of energy that is immediately usable.
Explanation;
-ATP is an unstable molecule which hydrolyzes to ADP and inorganic phosphate when it is in equilibrium with water. The high energy of this molecule comes from the two high-energy phosphate bonds. The bonds between phosphate molecules are called phosphoanhydride bonds.
-It only stores small amounts of energy by adding phosphate groups to the ADP molecules and then produces ATP. It can easily release and store the energy by breaking and re-forming the bonds between phosphate groups which is the basic energy source for cells.
