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.
The true statements about oxidative phosphorylation are the mechanisms of phosphorylation and oxidation are directly coupled.
<h3>
What is oxidative phosphorylation ?</h3>
- An electron transfer chain that is fueled by substrate oxidation and connected to ATP generation via an electrochemical transmembrane gradient is known as oxidative phosphorylation (OXPHOS).
- Cells employ enzymes to oxidize foods in the metabolic process known as oxidative phosphorylation, electron transport-linked phosphorylation, or terminal oxidation, which releases chemical energy to create adenosine triphosphate. This happens inside mitochondria in eukaryotes.
Steps in Oxidative Phosphorylation
- Electron Transport using NADH and FADH2. Near the start of the transport chain, reduced NADH and FADH2 transmit their electrons to molecules. ... the splitting of oxygen into water, proton pumping, electron transport, and ATP synthesis.

Answer:
Once the sun's energy reaches earth, it is intercepted first by the atmosphere. A small part of the sun's energy is directly absorbed, particularly by certain gases such as ozone and water vapor. Some of the sun's energy is reflected back to space by clouds and the earth's surface.
