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>

The answer to your question is A)front
<span>Here are the missing options for the above question:
</span><span>1. The bacterial culture in test tube D was diluted so much that no pink bacteria were left in the sample.
2. The pink bacteria were not able to get enough energy from the nutrient broth in test tube D to live.
3. The white bacteria outcompeted the pink bacteria for the nutrients in the broth in test tube D.
4. The pink bacteria are sediment growers in nutrient broth and the micropipette could not reach them.
