Answer:
The reason why, in cold temperatures and depending on the type of fatty acids, the phospholipid bilayer is less or more fluid is due to the different molecular interactions that occur between the tails of both types of fatty acids. the unsaturated - which determines the fluidity of the cell membrane.
Explanation:
<em>Temperature and saturation of fatty acid tails</em><em> are two factors that affect the </em><em>fluidity of the phospholipid bilayer</em><em> in cell membranes.</em>
Under normal conditions, low temperatures decrease the fluidity of the phospholipid bilayer, since it decreases the kinetic energy and increases the molecular interactions, which increases the stiffness.
However, unsaturated fatty acids - those that contain double bonds in their molecules - have a configuration that allows their tails to be more separated in their arrangement in the bilayer, which avoids the increase in molecular interactions and maintains to a certain extent the membrane fluidity, despite low temperatures.
The surgical procedure that uses a blood vessel from another part of the body to channel blood around an occluded coronary artery is the coronary Artery Bypass Graft. This is a procedure that restores blood flow to the heart muscle by diverting the flow of blood around a section of a blocked artery in the heart. Specialists use this procedure to treat people who have severe coronary heart disease, a disease in which a waxy substance called plaque builds up inside the coronary arteries.

In addition, </span><span>an ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. </span>
Well, i think it's not bacteria, its Hydrochloric Acid. For shakrs ITS REALLY STRONG, i hope this helps or answers your question! :) x
