What are the differences between isotonic hypotonic and hypertonic

isotonic: two solutions having the same osmotic pressure across a semipermeable membrane

hypertonic: shrink. solution is one in which the concentration of solutes is greater inside the cell than outside of it

hypotonic: swell. solution is one where the concentration of solutes is greater outside the cell than inside it

Explanation:

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
