Dilution means adding more solvent to a solution to lower down its concentration and in that process volume of solution expands. That means on diluting a solution the following parameters will change:
1. Amount of solvent
2. Total volume of the solution
3.Concentration of the solution
So the parameter that does not change is the amount of solute that will remain constant on diluting a solution, So here the the answer will be the amount of solute that will remain unchanged during dilution.
A neuron has 4 basic part the dendrites the cell body
I think the answer is b.the cell body
but the brain is made up of about 86 billion nerve cells also called neuron
Today I will explain what a valence electron is and how many valence electrons each of the atoms your asking about have. :)
→ A valence electron is an electron in the outer shell of an atom that is able to participate in bonding. While iodine has 53 electrons, all but seven are in the inner shells of the iodine atom.
→ Sulfur has sixteen electrons in total, two in the inner shell, eight in the middle, and six in the outer. This means that sulfur has six valence electrons.

Answer:
Boiling of a substance
Explanation:
When something is boiled, heat is released to the surrounding, making it an exothermic reaction (a type of chemical reaction)
