On the basis of Thomson’s model of an atom, explain how the atom is neutral as a
whole.

As per Thomson’s model of an atom, the number of electrons (negatively charged) are

equal to the number of protons (positively charged) in an atom. Hence the +ve and –ve

charges are neutralized by each other that makes atom neutral as a whole.

Explanation:

Accorrding to Thomson's model of the atom, an atom consists of both negatively and positively charged particles. The negatively charged particles are embedded in the positively charged sphere.. Thus, by counterbalancing each other's effect, they make an atom neutral.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

sex cells are usually half's then they find another half and make a fertilize egg
