Sandra examined some animal cells using a compound microscope. Under normal conditions, the cells have an approximate salinity of 1 M NaCl and resemble the slide shown in picture 1.

If the cells are submerged in pure distilled water, what will happen to the cells?

If the cells are submerged in pure distilled water, each cell will absorb water from the environment where it is located, increase its volume and possibly break.

Explanation:

The cells maintain an osmotic balance relationship between their cytoplasm and the extracellular space, that is, the cell is isotonic with the medium.

When a cell is exposed to a hypotonic medium -such as that which provides pure distilled water- water will pass through osmosis from the extracellular space to the cytoplasm, causing the cell to increase in volume (swell) and the increase in internal pressure can Make it break.

In osmosis, water passes from space with less concentration of solutes to the highest concentration.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
