The answer is; Pepsin
Pepsin is first secreted by the chief cells of the stomach wall and the inactive precursor called pepsinogen. When pepsinogen interacts with the acidic environment of the stomach due to hydrochloric acid, it is turned to pepsin. The pepsin breaks down large protein molecules to smaller molecules.
Darwin's book suggested that organisms evolve through natural selection.
An isotonic solution is when the solute concentration is balanced with the concentration inside the cell , the water movement still moves between the solution, but the rates are the same in both directions, the water is balanced inside and outside the cell .
A hypotonic solution is when the solute concentration is lower than the concentration inside the cell. water moves into the cell and can cause the cell to swell; cells that don’t have a cell wall, such as animal cells, could explode in this type of solution.
A hypertonic solution is when the solute concentration is higher than the concentration inside the cell. In a hypertonic solution, the water moves out of the cell and causes the cell to shrivel.
