Aplant cell shrinks from the lack of water what term describes the environment outside the cell?
permeable
hypertonic
hypotonic
osmotic

A hypertonic environment will result in cell shrinkage due to osmosis. However, this question is unclear because it's not the lack of water that causes shrinkage, it's the loss of cell water due to there being more concentrated aqueous particles outside of the cell vs. inside of the cell. I would still go with hypertonic though.

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)
