In which location of the digestive system will you find both physical AND chemical digestion?

The stomach

Explanation:

In the stomach, physical digestion occurs because of peristaltic contractions (wave like contraction in the lean muscle) and chemical digestion occurs because of stomach acid, hydrochloric acid, breaking down your food.

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
