All of these conditions can cause protein denaturation, except:
high temperatures from cooking.
digestion by pancreatic proteases.
the presence of hydrochloric acid.
a change in blood ph.
an increase in body temperature due to high fever.

The correct option is: an increase in body temperature due to high fever

Explanation:

Denaturation of protein is a process by which the protein unfolds i.e. loses it's quaternary, tertiary, and the secondary structure when exposed to high temperature (above 41°C), change in pH or chemical denaturants. Denaturation of proteins leads to loss of activity.

The enzymes pancreatic proteases breaks down proteins by hydrolysis, thus leading to the denaturation of protein.

Since, generally fever does not increase the body temperature above 41°C. Therefore, it doesn't lead to denaturation of protein.

more info ? ? i don't understand what the question is

explanation:

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
