Answer:
Photoperiodism
Explanation:
The process explained in the question is called "Photoperiodism" which refers to the plants' reaction to the length of the dark and light period in a day.
When the dark period is interrupted with a certain period of artificial lighting, the plant thinks that the day had a longer period where it's "light" than it is "dark" so it gets tricked into flowering. Same concept can be applied in reverse for the plants who flower during longer periods of dark.

The liver plays an important role in the food digestion. The liver secretes bile juice which helps in the digestion of the fats. In the absence of digestion, this bile is stored in the gall bladder. The bile juice is the yellowish fluid, which aids in the digestion of fats (occurring in the small intestine) by emulsifying the fats molecules. the emulsification of these fat molecules is critical for their digestion, and absorption. Hence, the liver secretes bile juice and acts to emulsify the fat in the lumen of the small intestine.
