What is the role of ATP when large molecules need to be transported across the cell membrane against the concentration gradient? The bond between the phosphate groups is broken to store energy.
The bond between the phosphate groups is broken to release energy.
Bonds are formed between the adenine and the ribose to store energy
Bonds are formed between the ribose and the phosphate to release energy.

b. the bond between the phosphate groups is broken to release energy

Explanation:

=> it's easy to break this bond & ATP is unstable

=> ATP has a lot of free energy

=> delta G <0

=> breaking this bond releases energy

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.  

the answer is z.

the human body has five levels of organization. level 1: cells. cells are the basic units of life and form the first level of organization. cells in the human body have specific functions. examples include nerve cells, blood cells, liver cells, and so on.
