Answer
The term that describes the pH in the stomach is 'Acidic'. The reason why the stomach is this pH is because it assists in the digestion of food by breaking down proteins and killing potential harmful bacteria.
Explanation
## Step 1: Understanding the pH scaleThe pH scale measures how acidic or basic a substance is. The scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic.## Step 2: Identifying the pH of the stomachThe pH level in the stomach is typically between 1.5 and 3.5, which is significantly acidic. ## Step 3: Reasoning for the acidic pH of the stomachThe stomach is acidic because it needs to break down food particles, especially proteins, into smaller, more manageable particles. This acidity also helps kill potential harmful bacteria that can be present in the ingested food.
