The Pa. Fish and Boat Commission wants acid rain gases reduced by 40%
<h3>What is Acid Rain?</h3>
Acid rain is formed by the precipitation of acid in the form of rain due to reaction of two atmospheric pollutants like oxides of nitrogen and Sulphur with rainwater.
The deposition of acids can occur either wet and dry way.
In wet deposition the precipitation removes acids from the atmosphere and place them on earth surface.
In dry method the deposition of gases and pollutants in the form of dust and smoke.
Man-made cause is the emission of gases from industries or by natural way like lightning which release nitrogen oxides and volcanic eruptions release Sulphur oxide.
The pH value of acid rain is around 5.7.

<span>Mutation cannot be predicted and research cannot determine when mutations will occur. However, natural selection indicates that species with the strongest traits will multiply more and live longer than their weaker counterparts. Therefore natural selection is systematic and predictable.</span>
Answer:
Explanation:
we have three strains.
the first is the wild type which has tryptophan mRNA which gets degraded rapidly and tryptophan synthase which is stable. therefore, in the presence of tryptophan, no new mRNA is formed and whatever tryptophan synthase was present would be diluted out as cells continue to divide.
Strain A has stable mRNA and stable tryptophan synthase. so since the mRNA is present, new enzyme will continue to form from it. However, since no new mRNA is formed, the enzyme activity will get diluted as cells divide, but at a much slower rate than the wild type.
in Strain B , synthase is rapidly degraded and no new mRNA is formed. so the tryptophan synthase activity would decrease drastically.
Answer: pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer. ... Meteorologists describe the atmospheric pressure by how high the mercury rises.
