Answer:
25% colorblind daughter: 25% colorblind son: 25% carrier daughters with normal vision: 25% normal son.
Explanation:
The genotype of a color-blind man is X^cY and the genotype of the heterozygous carrier female is X^cX. A cross between X^cY and X^cX would produce a progeny in following ratio=
25% colorblind daughter: 25% colorblind son: 25% carrier daughters with normal vision: 25% normal son.
Therefore, the couple is likely to have 50% normal son and 50% affected son. Likewise, the couple is likely to have 50% normal daughters and 50% colorblind daughters.

If a unicellular organism was exposed to a hypotonic solution for an extended period of time, it would gradually swell and burst. In a hypotonic solution, the amount of solutes are lesser outside the cell compared to inside of it. Water will move into the cell making the it bigger and eventually will result to its eruption.
