Answer:
As a river flows, it picks up sediment from the river bed, eroding banks, and debris on the water. The river mouth is where much of this gravel, sand, silt, and clay—called alluvium—is deposited. When large amounts of alluvium are deposited at the mouth of a river, a delta is formed.

Im pretty sure the answer is the atmosphere provides warmth.
Answer:
(+)-cholesterol = 71.88%
(-)-cholesterol = 28.12%
Explanation:
<em>Asuming 1 gram of sample is dissolved in 1mL of water and the sample cell was 1dm long.</em>
Enantiomeric excess is defined as the amount of pure enantiomer in a sample. The formula is:
ee = [α]mixture / [α]pure enantiomer.
Replacing:
ee = 14° / 32°×100 = 43.75%
As the sample is 14°, There is an excess of (+)-cholesterol and 56.25% is a 1:1 mixture of enantiomers.
That means percent composition of enantiomers is:
<h3>(+)-cholesterol = 43.75% + 56.25%/2 = 71.88%</h3><h3>(-)-cholesterol = 56.25%/2 = 28.12%</h3>
