Answer:
Both Cohesion and adhesion play an important role in the upward movement of water through a plant.
Explanation:
Water is absorbed by the roots and transported by xylem tissue to various parts of a plant body such as stem ,leaf .
During the transportation of water molecules through the xylem tissue formation of hydrogen bond occur between the water molecules. A single hydrogen bond is weak but collectively they exert a very strong interaction.As a result a water column is established in the xylem tissue. This is called cohesion.
Adhesion deals with the interaction of water column with the wall of the xylem tissue.
Rock salt is also known as halite. It is different to sea salt because it is already found in a solid form and then mined. Table salt (refined salt) can also be produced from solid salt which is found underground and then refined to remove any impurities.

<span>The correct answer is calcifediol or calcidiol.</span>
<span>It is a prehormone that is produced in the liver. The mechanism of production includes hydroxylation of vitamin D3 (cholecalciferol) by the enzyme cholecalciferol 25-hydroxylase. Because it is the major form of vitamin D in the blood, it is considered the best indicator of vitamin D status. Calcidiol is converted in the kidneys into calcitriol which is the active form of vitamin D. </span>
