How might a plant cell compensate for the excessive membrane fluidity that occurs during prolonged exposures to elevated temperature?A) Reduce membrane cholesterol content. B) Alter the lipid composition to have longer fatty acyl tails and fewer double bonds. C) Alter the lipid composition to have shorter fatty acyl tails and more double bonds. D) Alter the lipid composition to have shorter and more unsaturated fatty acyl tails. E) Reduce cholesterol content and alter the lipid composition to have shorter fatty acyl tails.

E) Reduce cholesterol content and alter the lipid composition to have shorter fatty acyl tails.

Explanation:

Reducing the amount of fat makes the tissues or membranes have less plasticity, since these fatty acids with high temperatures increase their fluidity, are less dense and give greater plasticity in their elastic modulus.

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.
