He demonstrated that SCD and sickle cell trait were due to the presence of abnormal 8-globin polypeptides in red blood cells. He demonstrated that the electrophhoretic mobility of B-globin from patients with SCD was different from that of healthy individuals. He demonstrated that both parents of multiple patients with SCD had low levels of sickled red blood cells. He hypothesized that SCD was a recessive trait and that the parents of patients with SCD would be heterozygous carriers. He demonstrated that the difference between B-globin polypeptides in individuals who were healthy and those with SCD is an amino acid substitution. He performed a peptide fingerprint analysis on B-globin from individuals with 84 84 and 89 88, which identified the segment of B-globin that was changed by the BS mutation.

Answer:
xylem cell and phloem cell
Answer:
All vascular plants have water-conducting tissue and are better adapted for life on land than the bryophytes; they are also characterized by a dominant sporophyte generation.
Answer:
Explanation below.
Explanation:
The movement will help the people to exercise more.
It should be understood that the presence of mosquitoes and the situation of the region as a wet region will not allow people to do much exercise, but their movement to the dry region will allow them to do more exercise than that of the wet region.
There is also a corresponding diffusion of Chinese and Japanese's forms along this zone
