A. Regularly test the water in residents' homes
Explanation:
The best way to have kept the water quality in check would have been to constantly and regularly test the water in residents' homes.
Lead is used in making pipes due to its very unique properties and availability. Over time, lead can enter the water it is carrying in dissolved form.
Increasing amount of lead in the water will eventually become toxic when an anomalous concentration is reached.
The best way to monitor the trend is to simply check the water in residential homes from time to time for dissolved lead.

Answer:
1/2 or 50%
Explanation:
Let us assume that the existence of heterozygous dark male means that the dark trait is dominant over the light trait. Hence, the light color trait is recessive.
Let us also assume that the dark color trait is represented by the allele A and the light color trait by allele a.
Heterozygous dark male = Aa
Light female = aa
Crossing the two:
Aa x aa
Aa Aa aa aa
Aa = dark color = 1/2 or 50%
aa = light color = 1/2 or 50%
<em>Hence, the probability of producing light-colored moths would be </em><em>1/2 </em><em>or </em><em>50%.</em>
