ehidna [41]

Theory of natural selection by Charles Darwin explains the moth appearance in England. The theory of genetics describes this as a mere shift of trait due to environmental factors.

<h3><u>Explanation:</u></h3>

Peppered moths are the moths found in England from a long time ago. The environment before the industrial revolution was pure and pollution free, which led to the growth of the white variety of moths as they were able to camouflage better with the bark of the trees from their hunters. The white trait were the parents, and fertilization between the two recessive traits gave rise to the recessive traits only.

But with the industrial revolution, the pollution increased to a huge extent, leading to deposition of smokes and soot on trees bark where white variety of the white moths got easily recognizable. This led to the black moths which now can camouflage better. Thus the nature selected black variety over white variety for better survival, and the white variety reduced dramatically.

Despite the human genome being significantly larger than the genome of bacteria such as E. Coli, it does not take a human cell s
ICE Princess25 [194]

Answer:

Rapidly and Accurately

Explanation:

As an example, eukaryotic human DNA replicates at a rate of 50 nucleotides per second.

Replication occurs so quickly because multiple polymerases<em>, or think: enzyme+polymer=polymerase,</em> can synthesize<em>, or combine or fuse,</em> two new strands at the same time by using each untwined strand from the original DNA double helix as a guide.

DNA replication is so much faster than bacteria replication because it's extremely difficult to replicate DNA accurately, as well as copying molecules that tightly complexed with histones in nucleosomes, which work together to form chromatin, which is the material that chromosomes are composed of, and it's further composed of protein (histones), DNA, and RNA.

Therefore, the reason for human cells taking significantly less time to replicate its genome is <u>accuracy</u>.
