Answer:
Change the number of neutrons in an atom and it becomes an isotope, change the number of electrons, it becomes an ion. When you change the number of protons in an atom, you will change the atom from one element to a different element. Sometimes, when you add a proton to an element, the element will become radioactive.

Answer: It becomes inactivated
Explanation:
Since enzymes are proteinous in nature, they perform best at a particular physiological temperature, pH and location.
So, once pepsin gets transferred to duodenum (where trypsin) is located, it becomes inactivated because it functions best in the acidic medium of gastric gland, whereas pancreas has an alkaline medium.
Thus, alkaline pH of the duodenum will coagulate and inactivate pepsin.

Answer:
In acid-fast staining, carbon fuchsin is used as a primary stain which dissolves the mycolic acid present in the cell wall of <em>Mycobacterium smegmatis </em>and penetrates through it which results in staining <em>Mycobacterium</em> red.
Staphylococcus aureus cell wall does not contain mycolic acid so carbon fuchsin does not penetrate its cell wall, therefore, it becomes colorless after destaining with acid alcohol.
After destaining step methylene blue is added to stain non-acid-fast bacteria blue. So if I mistakenly forgot to use methylene blue during the procedure <em>Mycobacterium smegmatis</em> will appear red due to carbon fuchsin present in their cell wall and S<em>taphylococcus aureus</em> will appear colorless because it is destained.
