In the human digestive system, particularly in the Esophagus digestion can not occur.
Esophagus, is a muscle tube that transports the unfinished meal from the mouth to the stomach for further absorption. As a result, the esophagus is one area of the digestive tract where digestion is not completed.
- Tube 1: HCl breaks down salivary amylase
- Tube 2: no digestive enzyme, no bile
- Tube 3: no pancreatic enzymes
- Tube 4: boiling denatures salivary amylase and absence of Pepsin.
Egg digestion occurs in the small intestine not in the Esophagus.
Pepsin digests egg white.
- Pepsin is a peptidase, a special enzyme with the function to degrade proteins into amino acids. Like all enzymes, pepsin is also a protein.
- The small intestine, where the majority of protein digestion takes place, receives the chyme from the stomach that contains the broken-down egg particles. More enzymes are present in the digestive juice the pancreas secretes, which further breaks down the protein fragments.

Founders' effect type of genetic drift occurs from adaptive radiation. thus option A is true.
<h3>What is genetic drift?</h3>
Genetic drift is an evolutionary process in which the frequency of a given gene allele varies randomly across a population.
The founder effect, which happens when a small group of people splits off from a larger population to form a colony, is yet another extreme illustration of drift.

Antibiotics are meant to kill living things (bacteria). Viruses, on the other hand, we are not sure if they would classify as living. Viruses change the meaning of "life" if we consider them alive. They can <em>only </em>reproduce within another cell by taking over that cell. An antibiotic would have to be able to kill human cells to kill a virus, and that would not be a good medicine to take. Viruses invade a host cell and incorporate the virus DNA into the host cell's DNA, which would cause the host cell to create more viruses to invade other cells. <span />
