Answer:
E. The 32P was associated with the bacterial cells and 35S was associated with the phage particles.
Explanation:
Hershey and Chase's experiment proved that DNA serves as the genetic material of the cell.
This experiment used the bacteriophage which could infect the bacteria by integrating its DNA into the bacterial genome. For this, he used radioactive phosphorus and radioactive sulphur.
Phosphorus is a constituent of the DNA and sulphur is the constituent of the proteins. This means if the DNA is transferred, then radioactive Phosphorus will be transferred but if proteins are transferred then radioactive sulphur is transferred.
He found the radioactive phosphorus attached to the bacteria and sulphur to the phage itself. This suggested that the DNA material is transferred and acts a hereditary material and not the protein.
Thus, Option-E is correct.
I guess it would be the sun?
Answer: Black allele has frequency of 0.14.
Red allele has frequency of 0.86.
The frequency of heterozygotes is 0.241
Explanation: <em>Hardy-Weinberg model </em>states the frequency of alleles in a population will stay in equilibrium as long as there are external influences. It is also used to determine alleles frequencies using the following equations:


p represents frequency of dominant allele;
q represents frequency of recessive allele;
2pq is frequency of heterozygotes;
For the frequency of red allele, which is dominant, we can use:




p = 0.86
For the black allele:



q = 0.14
Frequency of heterozygotes is
2pq = 2(0.86)(0.14)
2pq = 0.241
<u>Frequencies for a population of Muscovy ducks are </u><u>0.86 for red allele, 0.14 for black allele and 0.241 for heterozygote.</u>
