The correct answer is option D, that is since genetic drift is random, it does not always favor the better or healthier organisms.
A mechanism of evolution in which the frequencies of alleles of a population change with generations because of sampling error is known as genetic drift. It takes place in all the populations of non-infinite size, however, its influences are strongest in small populations.
<span>A drug used to treat CML, imatinib, binds to the active site of Abl kinase. Why does this drug work to treat this type of cancer?
</span><span>B) By binding to the active site, the drug prevents the ability of Abl kinase to bind to its substrate.

Imatinib works against CML by binding close to the ATP binding site of bcr-abl. The binding results to the<span> locking in of the bcr-abl to a closed or self-inhibited conformation and inhibiting the enzyme activity of the protein </span><span>semi-competitively.</span>
Answer:
<em>Light-dependent reactions</em>
<em></em>
Explanation:
Photosynthesis occurs in two stages: light-dependent reactions and light independent-reactions. This last stage is often called Calvin cycle.
The diagram shows reactions occurred in the thylakoid membranes which are located inside the chloroplasts. Therefore, we can identify that these reactions are the light-dependent reactions. During this part of photosynthesis, the energy from the sunlight is absorbed by a pigment called chlorophyl (Chl). Then, it is sequentially coverted into chemical energy stored in the form of molecules: NADPH (nitotinamide adenine dinucleotide phosphate) and ATP (adenosine triphosphate).
