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.

Gymnosperm plants important adaptation of the seed allowed plants to spread quickly across the land.
What is a gymnosperm ?
- Unlike angiosperms, or flowering plants, whose seeds are enclosed by fully developed ovaries, or fruits, gymnosperms, or any vascular plant, reproduce by the use of an exposed seed, or ovule.
- Many gymnosperms bear their seeds in cones, which are known as "raw seeds" because they are not visible until they are fully developed.
- Yew ,Gingko biloba, Cycads , Pines, Spruce are examples of gymnosperm
What is adaption in plants?
- Special characteristics that enable a plant or animal to survive in a specific location or habitat are known as adaptations.
- The plant can find it exceedingly challenging to live in a foreign environment because of these adaptations.
- This explains why some plants are only found in particular places.
