Digestion
Explanation:
The breakdown of foods into forms that can be transported to cells and absorb into these cells(this process has two parts): Mechanical(breaks down large pieces of food into smaller ones) and Deglutition(swallowing).
Answer:
A logarithmic scale condenses the range of acidity to numbers that are easy to use. Consider a solution with [H + ] = 1.0 × 10 -4 M. That is a hydrogen-ion concentration that is 1000 times higher than the concentration in pure water. The pH of such a solution is 4.00, a difference of just 3 pH units.
