Answer:

A, B, E

Explanation:

The guard cells block water loss (transpiration) when the cells are turgid. To become flaccid, the cells must lose water. This is accomplished when the surrounding cells accumulate K+ making them hypertonic compared to the guard cells. The guard cells then lose water via osmosis.

I think I understand even without the picture. I'll add a picture of the Punnett Square filled in, but what you're crossing is

Tt x tt (heterozygous crossed with a homozygous recessive)

The ratio you get in the end is 2 heterozygous (Tt) and 2 homozygous (tt) offspring, so the ratio is 1:1.

So the percentage of offspring that are homozygous recessive is 50%.
