The water enters the xylem first by osmosis. Water moves from the soil to the root hair cell down a water potential gradient, and to the root cortex cell from a higher water potential to a lower water potential, this process will be repeated until water enters xylem. Because transpiration is occurring in the leaf, water is lost so there is a lower water potential inside the leaf. Osmosis moves water from the xylem to the leaf because the xylem has a higher water potential. Water moves from the xylem to the cells of the leaf. This pulls water up the xylem via cohesion which is the process of water molecules attracting each other and sticking together. Water does not fall down the xylem as here is adhesion which is the process of water molecules sticking to the inside of the xylem.
Answer: The phosphate group has the chemical composition 
.
Explanation:
A phosphate group is a group where one phosphorus atom is attached to four oxygen atoms.
The oxygen atoms are attached to the phosphorus atom via single bond and one oxygen atom is attached to the phosphorus atom via double bond.
The chemical formula which represents a phosphate group is .
Thus, we can conclude that phosphate group has the chemical composition .
Answer:
<em>The water will diffuse into the air.</em>
Explanation:
Diffusion can be described as a process through which molecules travel from an area of higher concentration to an area of lower concentration along the concentration gradient. Such processes do not require energy. As the concentration of water is less in the air surrounding the cell as compared to the inside of the cell hence, the water molecules will move out of the vacuole and into the air by the process of diffusion.
The renewable energy source in all cells would be;
ATP (adenosine tri phosphate)
ATP is responsible for active transport, cellular respiration and many other cell activity. Cells would die without ATP and then so will the organism itself.
Answer:
1) Growth of the organism. An adult human being is made up of billions of cells and all cells have the same genetic component.
2) Repair. In the case of wound healing; that should be replaced with the same type of cells with the same genetic quality.
