Katyanochek1 [597]

Nucleosomes are composed of "histones" class of molecules.

<u>Explanation:</u>

Histones usually presented in eukaryotic nuclei of cells which seemed as strong level of proteins that bundle and organize DNA into structural groups called nucleosomes in biological science.

They are chromatin's chief protein elements, functioning as spools along which DNA spins, and playing a major role in regulating genes. Five forms of histones have been recognized:

  • H1 (or H5), H2A, H2B, H3, and H4;

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.

Which of the following results from cutting down trees
ZanzabumX [31]

Answer:

D

Explanation:

Vegetation on soil protects the soil from erosion because its roots and root hairs help bind the soil particles together. This occurs mechanically by binding soil into crumbs and also chemically by providing organic matter that binds the soil particle into humus that holds moisture. The soil becomes heavy to be carried off by wind erosion. Trees also break the down flow of water hence reducing the capacity of runoff to carry soil sediments.
