Oil-based food coloring used to make the letters, won't dissolve in water. According to some sources, oil-based food coloring is either insoluble or immiscible in water. Because it is present in more solutions, water serves as the universal solvent.
<h3>
Universal solvent:-</h3>
A substance that displaces most compounds is known as a universal solvent. Because it dissolves more chemicals than any other solvent, water is known as the universal solvent.
<h3>
What chemicals lack solvability?</h3>
Sand, plastic, wood, metal, glass, and cloth are examples of insoluble materials. At standard conditions of pressure and temperature, these compounds never dissolve in water or any other solvent. Other examples of insoluble materials are sugars and inorganic salts.

Answer:
The homologous chromosomes form fairs.
Answer:
When electron jumps from high energy level to lower energy level.
Explanation:
The elctronic transition from one energy level to another energy level within the atom, always involve energy transitions.
The energy released or absorbed by electronic transition is always discrete and is called as " Photon". It means when electron jumps from when energy level to another energy level the energy released or absorbed is treated as photon emitted or absorbed.
When an electron jumps from higher energy level to a lower energy level, a photon of specific wavelength and specific energy is emitted in other words we can say that energy is released or emitted.
The energy of photon emitted or absorbed is easily calculated using Rydberg Formula which is simply the energy difference between the two energy levels and is given as under;
Ephoton = Eo ( 1 / n1^2 - 1 / n2 ^ 2)
In the above formula n1 is the initial energy level of electron and n2 is the final energy level of electron.
Eo = 13.6 eV ( Here "o" in Eo is in subscripts)
In n1 and n2 1 and 2 are in the subscripts.
^ represents that the disgits after them are exponents.
So by just putting the values of energy levels n1 and n2 we can easily calculate the value of energy of photon ( energy due to electronic transition) and compare the results that which transition will give high energy photon and which will give low energy photon.
