A pea plant with the genotype of TT was crossed with a pea plant with a genotype of tt. Tall is dominant and short is recessive. What percentage of the pea plants will be tall from this cross?

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:

Is 343 in the sequence -5, -2, 1, 4, 7
