Do biomolecules play a role in the passing of gas?

Yes.

Explanation:

Yes, biomolecules such as proteins play a key role in the passing of gas. In the cell membrane of a cell, there are some proteins are present which helps in the transportation of gases and water molecules through a semi permeable membrane of a cell. Transport proteins are a type of protein which helps to move molecules across the cell membrane with the expenditure or without the expenditure of energy.

the backbone of the dna and rna compound is sugar phosphate.

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.
