HEYA !!!!
Under normal light conditions auxins are spread out in the plant. But when sunlight varies, auxin is broken down on the sunnier side of the stem. The higher concentration of auxin on the shady side causes the plant cells on that side to grow more so it bendstoward the light.
Hope it helps you..

It is B has nothing to do with migration or water plants.
Answer:
The spreading of liquid or gases more widely
Explanation:
Answer:
When light energy is absorbed at that time the system gets excited which result in the conversion of light energy to chemical energy which is utilized by the system to do work.
Explanation:
When light energy is absorbed by a system at that time the molecules present in the system becomes excited by gaining energy.
The excited molecules then return to its original ground state by releasing energy which is in turn absorbed by adjacent molecules.
Thus the light energy is transferred from from excited molecule to the ground state molecule by converting itself into chemical energy.
Earths atmosphere is made up of a mixture of nitrogen (78%), oxygen (21%), and other gases (1%). There are 5 layers to the Earths atmosphere: Exosphere: 700 to 10,000 km, Thermosphere: 80 to 700 km, Mesosphere: 50 to 80 km, Stratosphere: 12 to 50 km, Troposphere: 0 to 12 km.The atmosphere becomes thinner until it gradually reaches space.
