Fracking can contaminate water supplies if it is not done properly, because the fracking fluid injected into rock to enable gas to be released often contains chemicals. If the borehole is not properly cased to stop leaks, the fracking water can escape into the aquifer
House sparrows in the northern part of North America are larger than those found in the southern regions. The possible mechanism of microevolution is more likely to be responsible for this is natural selection. The answer would be letter B.

Answer:
<em>make a gene from the given mRNA without the introns.</em>
Explanation:
Introns can be described as the non- coding regions of DNA. As they are non- coding, they are spliced out from the mRNA so that only the coding regions can be translated.
If we know a nucleotide sequence, then we can make a gene from it without added the introns. We can consider an mRNA strand and make a complementary strand from it, excluding the intron regions. Then from the DNA produced, we can make an mRNA without the introns and insert it into a bacterium.
