The peppered moth population in a locality has light and dark moth varieties. what is the likely cause of a relatively lower population of dark moth variety in the locality? a pollution-free environment increasing lichen growth. b highly polluted environment increasing lichen growth. c pollution-free environment covering the barks with black soot. d highly polluted environment covering the barks with black soot.

Answer: Option A Pollution free environment increasing lichen growth.

Explanation :

Thus, in a pollution free environment the lichen growth will increase and thus, the dark moths will find it difficult to camouflage and hence, there population will decrease.

its like this, "if i give a plant an unlimited amount of sunlight,then the plant will grow to its largest possible size."

hope it let me know if it does or doesn't =^-^=

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
