Answer:
The correct answer is D. maintain membrane fluidity through its disruption of fatty acid packing.
Explanation:
<u>Cholesterol</u> is a steroid lipid and is a constituent of biological membranes. It regulates the <em>fluidity</em> of the membrane (so, option C is not correct). Since cell membranes are composed of another type of lipids, the phospholipids, which form a bilayer, cholesterol distributes between the phospholipid tails and avoids these molecules pack each other forming rigid clusters. Thus, the option which better explains the effect is <em>D. maintain membrane fluidity through its disruption of fatty acid packing.</em>
Answer: 3
Explanation:
Given :
numC = 12
while numC > 3:
numC = numC / 2
Initial value of numC = 12
The condition checks if the value of numC is greater than 12, only then will the statement be executed and the loop isn't altered
numC = 12 is greater Than 3 ;
numC = numC/2 = 12/2 = 6
numC is now 6 ;
numC = 6 is greater than 3
numC = numC / 2 = 6/2
numC is now 3
numC = 3 is not greater than 3 ; hence, loop terminates (condition isn't met)
Hence , numC = 3
Answer:
No, mutations do not all result in negative effects. Sometimes they can be beneficial, as they are completely random. It is our general tendency to think of the word "mutation" in negative terms; however, do not get confused. Mutations are the root/ultimate source of genetic variation; they are one of the main factors that allow populations to evolve.
