Answer: 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.
Answer:
Option B, may allow bypass of a blocked coronary artery.
Explanation:
Collateral circulation consists of a network of tiny blood vessels which are nit functional under normal conditions. However, they become functional in case of coronary artery disease.
In coronary artery disease, the coronary arteries narrow down leading to blockage and stopping the flow of blood in the muscles of heart.
In this condition, the collateral circulatory network allows flow of blood around and within the blocked artery thereby protecting heart tissue from injury
Hence, option B is correct
