Answer:
The change in color in the flowers is because the plant has absorbed the dyed water. After some hours, we can see that the water has ascended through the roots, the stem and reached the flower petals. We can see the water's path till it evaporates in a process called transpiration, which returns water to the atmosphere.
Explanation:
Plants absorb water and other nutrients so that they can live. When we add ink into the water, we can see the water's path from the roots, up the stem, the leaves, and the flowers. In the flowers, the water evaporates through the stomata. We call this process transpiration. The ink allows us to see that the water was in the petals, but it evaporates, leaving behind the ink. As water evaporates, the plant drinks more, which results in a more intense color in the petals.

Sympathetic division is responsible for the nervousness, pounding in the chest and the butterfly movement in the stomach while parasympathetic division overest a and digest the nervousness.
Explanation:
The nervousness experienced when someone is about to speak in front of a class is caused by the sympathetic system which have divergent effects as many different effector organs are activated together for that same purpose. I.e More oxygen are inhaled and delivered to skeletal muscle. The respiratory, cardiovascular, and musculoskeletal systems are all activated at the same time causing an unstable reaction to the central nervous system...
On the other hand, the parasymthetic division causes the central nervous system to rest and digest at a very slow rate..
At a point in time the central nervous system triggered an Homeostasis action which posses a balance between the two divisions.I.e symthetic and parasymthetic and then brings about a balance to the body reaction at that same point.
