Imagine you have been shipwrecked and are floating on a small piece of wood in the middle of the ocean. You are terribly thirsty and take a drink of seawater (3.5% salt). What do you think happens to your stomach cells (1% salt), and why?

Respuesta :

Given the higher salinity of the ocean water in comparison to your stomach cells, you will lose water from your cells and become dehydrated.

Osmosis is a phenomenon that shows that in the presence of a space in which the solute concentration is higher than its current location, water will travel towards that more concentrated space in an attempt to dilute the concentration.

The urge to drink is what we call being thirsty. This urge has a biological origin. It is the body's way of telling you that your cells need more water, which leads us to often consume any water we have available. This is not always in our best interest.

However, due to osmosis, drinking the seawater would only have a negative effect on your stomach cells. As stated in the question, the cells contain less concentration of solute (in this case salt) than the water. This means that instead of entering the cell, water would leave to dilute the new seawater, thus dehydrating you more and worsening your condition.
