Prokaryotes lack an organized nucleus and other membrane-bound organelles, the prokaryotic DNA is found in the central part of the cell called the nucleons, the cell size ranges from 0.1 to 5.0 in diameter, the cell wall of a prokaryote acts as an extra layer of protection, helps maintain cell shoe and prevents dehydration.
Gastric ulcer is nothing more than an injury to the tissue lining the stomach. It may also be called peptic ulcer or stomach ulcer.

The best way to prevent an ulcer contraction is to maintain hygiene habits to prevent <em>Helicobacter pylori</em> infection. It is also good to avoid excessive consumption of alcohol, smoking and medications such as pain killers.
Create an experiment for this question: How is stomach acid neutralized in the small intestine?
Answer: As we already know it is the pancreas that manufactures enzymes that digest nutrients and releases bicarbonate to neutralize acid chyme that enters the small intestine. An experiment that could be performed to answer this would be to put in a glass flask bicarbonate soda. Then cover it with a balloon to turn it upside down and fill the balloon with the bicarbonate soda. Next you add vinegar to the flask and put back the balloon and slowly pour the bicarbonate soda and see the neutralization reaction that will take place.
I hope it helps, Regards.
I think that cell wall is used to support
