Answer:
The correct option is D. The nerve and red blood cells will turn on and off different portions of their DNA, using different genes to make different proteins.
Explanation:
A zygote is totipotent which means it has the ability to differentiate into any cell type found in the body along with the placental cells.
The nerve and red blood cells are specialized cells and they cannot differentiate into any other cell type.
All cells in the body are formed from the zygote. All the cells in the body have the same chromosomes and the same genes. However, these cells become specialized because certain part of the DNA is activated in one type of cell which helps it perform its function. Different genes are activated in different specialized cells which are able to transcribe and translate.

Answer:
Fossil fuels are hydrocarbons, primarily coal, fuel oil or natural gas, formed from the remains of dead plants and animals. In common dialogue, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived from animal or plant sources.
The pH of stomach is important as it helps to induce the digestive enzyme called pepsin. The presence of HCL i.e., hydrochloric acids in stomach results in the pH of stomach to become acidic which range from 1.5 to 6.5 values.
<h3>What is the pH level of stomach?</h3>
When the bolus enters the stomach, it aids the release of gastric juice having enzymes, mucous and HCL.
The upper and lower parts of stomach have varying pH values. Upper part has a pH of 4−6.5, while the lower part is with a pH of 1.5−4.0 which is highly acidic due to HCL.
Thus, the relative pH of stomach is acidic ranging from value 1.5 to 6.5.
