The reason why Hershey and Chase labeled the viral DNA with radioactive phosphorous and not radioactive sulfur is because A) DNA contains phosphorous and no sulfur.
Use this:
pH = 7 => neutral
pH > 7 => basic (alkaline)
pH < 7 => acidic
So, a pH of 7.6 means the soil is alkaline.
Now, to reduce the impact you should lower the pH.
Sulfur forms acid (H2S or H2SO4) which will lower the pH.
So, adding sulfur will result in the (at least partial) neutralization of the pH and so reduce the impact on plant growth.
Answers: 1) alkaline, 2) sulfur.

<span>The correct answer is b. will have a one-quarter chance of being a sickle-cell-free homozygote.</span>
<span>Sickle-cell disease is an autosomal recessive disease, which means that <span>if two individuals who are heterozygous for the sickle-cell disease have child, there is a 25% chance of sickle-cell disease, 25% that the child will not carry any sickle-cell alleles, and 50% that it will have the heterozygous condition (will have an allele for disease).</span></span>
