The parents are of genotype heterozygous dominant and homozygous recessive. Supposing the dominant allele is N and the recessive allele is n, one of the parents will be Nn while the other nn. The phenotypic (based on visible characteristics) ratio will be 1:1 for dom/rec and rec/rec as indicated in the diagram below.

The molecules in ice are close together and do not have any movement, or energy at all (frozen). The molecules in water are apart from each other and do have motion and energy. The molecule in gas or vaporization, are far apart from each other, have rapid movement, and have a great amount of energy. Just think that the lighter the liquid state of matter gets, the more energy and motion it has.
The answer to the question presented above would be 'require frequent rainfall'. A plant native to the chaparral would be expected to require frequent rainfall. This is because it cannot survive in dry lands and without constant water.
