Soil can get swept away into the water (by wind, gravity, rain, etc) and can increase the water level of the body of water.

A is wrong. Solutions are homogeneous.
B and C are wrong. The statements are correct, but they are not the reason why reactions are carried out in solution.
D is wrong. Chemical reactions do not always produce a colour change.
F is wrong. Some chemicals react with water, so other (often flammable) solvents must be used.
Answer:
I beleive it is A
Explanation:
we can infer that the male traits are homogenous dominants
BB for black and the females genes are heterogenous dominant or homogenous recessive. Ww or
