If your blood becomes too diluted, what will happen to the red blood cells?

The red blood cells will burst or rupture when it is diluted and it will be one transparent and visible.

Explanation:

This is because when red blood cells are in water or become too diluted,water will enter the red blood cells through the process of osmosis. Because water is an hypotonic solution, water from outside of the cell to the inside making the cells to continue to swell up and rupture ,a phenomenon known as haemylosis. When the red blood cells rupture, it loses haemoglobin and it's become transparent and visible.

i'd say that the moon rock is about 2.2 billion years old.
