Answer: B
Explanation: The salt water is isotonic because there is no mass change in the egg.
Part A: Water molecules are polar, meaning that they are neutrally charged overall, but with partial positive charges on the H atoms and a partial negative charge on the O atom. Thus, polar molecules like the salt, are like the water, neutrally charged and its ions interact with both the partially positive and partially negative parts of the H2O molecules.
Part B: In a dissolution of salt in water, the solvent is the water and solute is the salt. Solvent is a substance that allows the dispersion of another substance in itself, like the water in this solution. A solute is a substance that can be dissolved, dispersed in a solvent.

Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
