Answer is A. Calvin cycle.
Calvin cycle reactions or light independent process of photosynthesis occurs in the stroma (Ground substance) of the chloroplast. In the stroma enzymes are present for the Calvin cycle reactions. Carbon dioxide (CO₂) enters into the leaves through stomata and diffuses into stroma of the chloroplast. In the stroma carbon atoms from CO₂ is fixed into sugar (carbohydrate) with the help of energy from ATP and NADPH.
Clouds appear white because of scattering. The droplets in the clouds are huge compared to the wave length of light, so all wavelengths scatter at the same time. Hope this helps! :)
Im not sure the answer is there
Founders' effect type of genetic drift occurs from adaptive radiation. thus option A is true.
<h3>What is genetic drift?</h3>
Genetic drift is an evolutionary process in which the frequency of a given gene allele varies randomly across a population.
The founder effect, which happens when a small group of people splits off from a larger population to form a colony, is yet another extreme illustration of drift.
