Which of the following statements is true?
a. the most common type of lipids in membranes is sphingolipids.
b. the lipid bilayer is a stable, unchanging structure.
c. phosphoglycerides provide most of the structure and stability to cellular membranes.
d. all membrane lipids are amphipathic.

All membrane lipids are amphipathic

Explanation:

The membrane lipid molecules are amphathic in nature which states that they are both hydrophobic and hydrophillic part. The lipid bi layer has been found tot be the most widely found in cell structure.

The structure is made of phosphorus and lipids and hence called as phospholipids.

The amphipathic nature of the lipids allows it to assemble spontaneously into bi layers even under the artificial conditions.

hence, all the lipids in the cell membrane or membranes are amphipathic in nature.

i think the answer is gold im not entirely sure

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
