The answer is that a unicellular organism would swell and burst.
In a hypotonic solution <span>the </span>water concentration<span> of the cell's cytoplasm is </span>lower<span> then that of the hypotonic solution. If unicellular organism is exposed to a hypotonic solution, the water from the solution will enter the organism by the process called osmosis. The aim is to balance water concentration on the inside and outside of the organism. But, that water entering the cytoplasm of the cell will make pressure on the cell membrane. If the </span><span>excess water cannot be removed from the organism, it will swell and burst.</span>
A solution that has a pH of 6.8
it is <em>acidic</em><em> </em>as it has got ph value less than 7....But as it has got ph value near to 7 it is weak acidic..
Yes, most Bacteria are too small to be seen without microscope hope this is helped
