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.
That is true, enzymes are specific.
Answer: REABSORPTION
Explanation: Reabsorption or tubular reabsorption is one of the processes involved in urine formation,the other two(2) being ultra filteration and and active secretion.
Reabsorption takes place mainly in the proximal convulated tubule of the nephron, nearly all of the water, glucose, potassium, and amino acids lost during glomerular filtration re-enter the blood from the renal tubules,moving solutes out of the filtrate and back into the bloodstream.these solutes that are moved back into the bloodstream goes back into circulation alongside with the blood because it is needed for the normal functioning of the body system and maintanance of homeostasis.
In a situation where tubular reabsorption does not occur as a result of certain conditions like hyposecretion and diabetes insipidus,there will be imbalance of ions in the body as a result of useful ions leaving the body via urine and the body is left with ion deficiency.
