The ratio of tall to short in the second or the F2 generation was 3:1. Because the resulting genotype of the F1 generation would be Pp. If you test cross that and put in into a Punnet square, you would have three blocks that have the dominant trait and one block without. Remember that the dominant trait is always expressed. So three of them would be tall and one would be short. 

You answer is then D.

Briefly describe what occurs when a red blood cell is placed in water (a hypotonic solution).
AleksandrR [38]
When a red blood cell is placed in water, the water molecules will enter the cell rapidly as a result of osmosis. Osmosis is the process by which molecules moves through a cell permeable membrane from the region of lower concentration to that of higher concentration.
The inside of the red blood cell is more concentrated than the water in which it is placed, so water will move into the cell via osmosis. 
This will make the cell to swell up and to burst open.<span />
