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.

Answer:
by comparing external features, behaviors, or physiology of organisms that enhance their survival such as migration, hibernation, or storage of food in a bulb.
Explanation:
Answer: 1. Lipophobic
2.Thyroid
3.lipophilic
Explanation:
Chemical messengers can be classified by their chemical characteristics including their solubility in water and their chemical structure.
Depending on their solubility in water they can be classified in two groups:
- Hydrophobic (lipophilic) - Molecules are lipid soluble and can easily cross the plasma membrane.
- Hydrophilic (lipophobic) - Molecules that are water soluble and do not readily cross the plasma membrane.
Depending on the chemical structure
Amino Acids are lipophobic.
Amines are derived from amino acids and contain an amine group (-NH2, known as the amino group). An important group of these are the catecholamines which contain a 6 carbon ring (catechol) and are derived from tyrosine. These include dopamine, norepinephrine and epinephrine. The thyroid hormone is derived from tyrosine. All except thyroid hormones are hydrophilic. The thyroid hormone is lipophilic (hidrophobic)
