How do the differences between cells produced by meiosis and mitosis lead to changes in the next generation?

smaller cell membranes

because meiosis produces fewer viable cells than mitosis, organisms made with cells from meiosis will be less healthy the next generation will have smaller cells because cells produced by meiosis have smaller cell membranes than cells produced by mitosis

not sure if this what   you'r looking for would be percent composition

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
