The mouth is the beginning of the digestive tract. In fact,digestion starts here as soon as you take the first bite of a meal. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use.

The mouth is the beginning of the digestive tract, chewing breaks down the food into pieces so it is easier to digest. The throat is the next destination for food, from here food travels to the esophagus. The esophagus is a muscular tube extending from the pharynx to the stomach. The stomach is a sac like organ with strong muscular walls. The stomach secretes acid and powerful enzymes that continues the process of breaking down food. When it leaves the stomach it is a liquid or paste. From there it moves to the small intestine. The small intestine is made up of three segments. The duodenum, jejunum, and ileum, the small intestine is a long tube loosely coiled in the abdomen.

Suppose a new mutation that improves metabolic efficiency is lost from a small population of mammals living in a region of seaso

Troyanec [42]

Answer:

C) genetic drift.

Explanation:

Genetic drift is the random change in the frequency of alleles in a population due to random sampling. Many circumstances can lead to genetic drift for example bottleneck effect, founder effect, etc.

The bottleneck effect occurs when most of the members of a population die because of any natural disaster like flood, fire, etc. This can cause a certain allele to be lost in the remaining population because of losing major populations. So here due to hurricane half of the mammal population gets eliminated which shows it is an example of the genetic drift.

it takes light from the sun about three minutes to reach mercury how many hours does it take light from the sun to reach Neptune

Kazeer [188]

The time taken to reach the Neptune planet is 4.2 hours

<h3>What is the time taken?</h3>

We can see that the speed of light has the value of 6.7 * 10^8 miles per hour . We also know that the solar system is composed of the sun and the planets. The distance of the between the sun and mercury is 35,000,000 miles while the distance between the sun and Neptune is 2.8 x 10^9 miles.

This implies that the ratio of the distance from neptune to the sun and that of mercury to the sun is; 2.8 x 10^9 miles/3.5 * 10^7 miles hence Neptune is eight times farther from the sun than mercury.

The time taken for light to reach Neptune from the moon is;

Distance = 2.8 x 10^9 miles

Speed = 6.7 * 10^8

Time = 2.8 x 10^9 miles/6.7 * 10^8

= 4.2 hours
