3. Make a claim about what you think the average pH is in your intestine. Give evidence from the graph to support your claim.

The intestinal pH is a neutral pH, that is, 7.

If this pH is not met, it does not tend to neutralize the stomach enzymes will not be regulated, that is to say that when we digest the food bolus the gastric enzymes that are dumped together with the food in the form of chyme to the intestine are active because the low pH and the acidic medium is what triggers its action, when encountering intestinal neutrality that ranges from 5 to 8 in terms of pH, these enzymes are inactivated and stop working at the intestinal level, giving rise to the activation of intestinal juices.

Explanation:

https://pubmed.ncbi.nlm.nih.gov/21947475/ in this link I leave you a scientific evidence of pubmed associated with how intestinal pH is regulated through the mucus that is secreted in it and even how it is related to it bacterial growth of both commensal flora and other bacteria.

The intestinal pH is essential to be maintained since it regulates the immune system, the predominant commensal flora that protects us from serious opportunistic infections and the enzymatic activity that helps us assimilate nutrients, it is essential to note that in the intestine is where more absorption of Nutrients are fulfilled compared to the rest of the organs of the gastrointestinal tract.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
