Explanation:
The cell membrane constitute the phospholipid bilayer, proteins and small amounts of carbohydrates. The unsaturated fatty acids contain the double and triple bond in its structure.
The introduction of double bond introduces the kink in its structure and makes the membrane less rigid. This prevents the packaging of the lipid tightly and makes the membrane more permeable. This makes the membrane more fluid even at the lower temperature.
Thus, the correct answer is option (E).
Hello, Leah082656. There are many heated arguments over discussing stem cell research because of these two moral principals: the duty to prevent or alleviate suffering and the duty to respect the value of human life. In order to get embryonic stem cells, the embryo has to be destroyed. Although this is a huge controversial problem, by researching this could actually save and treat many other people. Some people are for it because it saves multiple people in the process, and some do not like this because it is killing an embryo. Whatever your stance is on this debate, these are the two sides that people debate over. I hope I helped!! Have a great day. :)
