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:
2nd answer
Explanation:
potential energy is stored energy
The general shape of the epithelial cells that are nearest
to the lumen in an empty urinary bladder is in multiple cell layers which are
considered to be a stratified tissue and the cells in it are shaped in terms of
the organ’s distention. This type of epithelial cell is the transitional
epithelium.
Answer:
There are four major classes of biological macromolecules.1.)carbohydrates 2.)lipids 3.)proteins 4.)nuclic acids .each is an important cell component a performs a wide array of functions.
