Answer:
C
Explanation:
A Smoke travels directly into clouds, creating acid rain.
B Smoke turns clouds black, which causes them to become more acidic and release black acid rain.
с Smoke increases greenhouse gases, which make the water in clouds more acidic so they release acid rain.
D Smoke wipes out all the greenhouse gases in the atmosphere, increasing the acidity of clouds so they create acid rain.
<em>The correct answer would be that </em><u><em>smoke increases greenhouse gases, which make the water in clouds more acidic so they release acid rain.
</em></u>
A typical smoke consists of a mixture of gases, including greenhouse gases like methane, water vapor, and some oxides of acids. Hence, smoke has the capacity to cause acid rain because it increases the concentration of greenhouse gases in the atmosphere. These gases dissolve in rainwater, causing it to form a weak solution of acid.
The correct option is C.

Answer:
0.25%
Explanation:
20 people start the new population. So there are 20 genes or 40 alleles for the recessive disorder phenylketonuria. 2 out of 40 alleles are recessive for the condition hence frequency of the allele = 2/40 = 0.05
Frequency of the allele does not change when the population increases so it is in Hardy-Weinberg equilibrium. According to it, if q is the frequency of recessive allele, q² = frequency of the recessive condition
Here, q = 0.05 So,
q² = (0.05)² = 0.0025
In percentage, it is 100 * 0.0025 = 0.25%
Hence, incidence of phenylketonuria in the new population is 0.25%
C. Light travels faster than sound
The change where they didn't only have boys anymore but had a boy which was born was more likely due to the fact that there is generally a 50:50% chance of whether a boy or a giril will be born for any given family.
