The correct answer is As oceans get hotter, they release more CO2, which then increases atmospheric and ocean temperatures.
<span>
Positive feedback<span> is a process which can be explained like this: </span>A produces more of B which in turn produces more of A.</span> <span>In the example above, high-temperature oceans (A) produce CO2 (B) which then make temperature even higher (A).</span>
When an area is malaria-free, the HbS allele frequency is between 0 and 2.02. Thus, option "A" is correct.
<h3>How, explain your answer briefly?</h3>
In the two maps that show the allele frequency of sickle haemoglobin (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 colour 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.

Answer: Moving from red light to violet light, the energy increases. From equation 1 and 2, we say that energy is directly proportional to frequency and inversely proportional to wavelength.
