<span> Embryonic stem cell research is kind of a dead area now since there is no way to control the differentiation. Most research is being done on adult stem cells to help map and control the differentiation process.
Stem-cells from aborted fetuses - The government doesn't sponsor this, if it is done it is by private companies not located in the USA. You could try researching umbilical cord stem cells to be somewhere near your topic. They come from the afterbirth of normal deliveries.
You could do a much easier report by covering cloning of mice through stem-cell technology. It is happening and helping scientists understand diseases. </span>

Answer:
All biological enzymes function best at particular pH values (most require pH 6 to 7) in the human stomach, the pH of 2-3 provides the environment required for the proper functioning of the digestive enzymes found there and this is the perfect condition for preservation of food and digestion of food.
Explanation:
The adding of basic material decrease acidity that happens due to the lower pH of the stomach. The very common basic material which is used to neutralize the acidity of stomach milk of magnesia.
The lower pH of the stomach cause acidity which is injurious to the health and also the mucous lining of the stomach. To balance is acidity milk of magnesia is required.
