Polaris (aka the North Star) has a radius of around 22 million miles, which is about 50 times the size of our sun!
Answer:
<em>The correct option is C) 1 only</em>
Explanation:
It would be necessary to ask from the scientist about the group of people on which he performed his experiment because it might be that certain other factor was the influence for the change in the requirement of Vitamin E, It might be that the people of that specific area or country might have a Vitamin E deficiency due to which there requirement was more for Vitamin E. Or there might be any other environmental or genetic factor influencing the change.

Answer:
C)Parental: 41% Dr, 41% dR; recombinant: 9% DR, 9% dr.
Explanation:
The notation Dr/dR for genotypes means that one homologous chromosome has the alleles Dr and the other homologous chromosome has the alleles dR.
The heterozygous plant Dr/dR will produce 4 types of gametes: two identical to the chromosmes the individual has in its somatic cells (called parental), and two gametes which will be a mix of the alleles in the homologous chromosomes (called recombinant).
- Dr: parental
- dR: parental
- DR: recombinant
- dr: recombinant
To calculate the frequency of each type of gamete, we must use the formula:
Distance (map units) / 100 = frequency of recombination.
18 mu / 100 = 0.18.
The total frequency of recombination between the genes D and R is 0.18, but every time crossing over happens, two recombinant gametes are generated. Therefore, each recombinant gamete will have a frequency of 0.18/2=0.09 = 9%.
The frequency of parental gametes will be:
1 - frequency of recombinant gametes
1 - 0.18 = 0.82
But there are 2 parental gametes, so each of them will have a frequency of 0.82/2=0.41 = 41%.
