The best answer is)
<span>It enables photosynthesis by facilitating primary growth of the plant.
The apical meristems are similar to stem cells in humans, and continue dividing indefinitely over the life of the plant. The cells are unspecialized, and only become specialized after being created. Apical meristems are the primary meristems, and constitute the primary growth of the plant, growing into organs such as leafs, flowers, and roots. </span>
Answer:
Because there is a mutation in region one that causes high level expression even in the absence of ethanol, region 1 must bind a transcriptional repressor and regulation of gene X must occur by relief of repression. Since a mutation in gene 2 results in a uninducibility of the gene, region 2 must bind a transcriptional activator. in the absenece of an activator the reprssor becomes irrelevant and the gene is in active regadless of conditions. Mutations in both regions 1 and 2 have the same effect as a single mutation in region 2, because in the absence of a bound transcriptional activator the repressor is irrelaevnat and the gene is inactive regardless of the presence or absence of ethanol
