Answer:
As the amount of impervious paved surfaces increase, watersheds become more vulnerable to pollutants. When rains fall on a conventionally paved impervious surface, the precipitation is generally directed down storm drains, which can result in flooding and overwhelming the storm water management system.

Answer:
The second one.
Explanation:
Purpose, hypothesis, procedure, data, analysis, and conclusion.
The phenotype is - 75 % red and 25 %brown.
The genotype is hRhR - 25%
hBkhR - 50%
hBrhBk - 25%.
<h3><u>Explanation:</u></h3>
The cross given here is a simple dominant - recessive relationship between the three types of alleles of hair colour. The genes of this characteristics are present in autosomes, so will be segregated equally among all the sexes of the offsprings.
Now the genotype of auburn and red with black mother is given. So during gametogenesis, the gametes from the parents will be
Father - hBr and hR
Mother - hBk and hR
So, the probable combinations are hBrhBk, hBrhR and hBkhR.
The frequency of the combinations are 25%, 25% and 50% respectively.
The phenotypic ratio will be red : brown as 3:1.
