Answer:
Active uptake (which I think you mean active transport) is important when the concentration gradient is against that of a certain substance, so it doesn't cross the membrane through diffusion or passive transport. It is sometimes necessary if a substance needs to move across a membrane but can't do so due to electrical charge or that there is a substance on the other side of the membrane preventing diffusion.

The phenotypic outcome will be pink. Incomplete dominance means none of the traits are dominant, therefore they will not mask each other. As a result, they will produce a new trait. In the case of the snapdragons, red + white = pink.
Genotypic wise, all of the offspring will be heterozygous.
