In the two maps that show the allele frequency of sickled hemoglobin (HbS) and malaria endemicity in Africa, it can be seen that in the regions with no malarial outbreak or malaria-free areas coincide with the grey to lighter shades of red in the heat map of the allele frequency of HbS. The color coding in the heat map for the allele frequency tells us that the frequencies range from 0 to 2.02 in the malaria-free areas.
Hence the answer is A)When an area is malaria free, the HbS allele frequency is between 0 and 2.02.
As ribosomes make their proteins, they may attach to the rough ER and insert the protein into the interior of the ER. The ER then begins folding the new proteins and transports them to areas in which chemical processing takes place
