Cholesterol is an organic steroid in mammalian cells that controls membrane permeability and fluidity. how many hydrigens

Hello. This question is incomplete. The complete question would be:

"Cholesterol is an organic steroid in mammalian cells that controls membrane permeability and fluidity. How many hydrigens are in cholesterol?"

46

Explanation:

Cholesterol contains carbon, hydrogen and oxygen atoms, and its molecular form is C27H46O, which means that cholesterol has 27 carbon atoms and 46 hydrogen atoms. Its structure consists of a region of 4 hydrocarbon rings attached to a hydroxyl group at one end and a hydrocarbon tail at the other. The hydroxyl group is the only hydrophilic part of the molecule, which makes it insoluble in blood as mentioned above.

The structure of cholesterol can be seen in the image below.

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.
