Explanation:
Prokaryotes: do not have a nucleus, use starch for energy, smaller ribosomes (70s)
eukaryotes: do have a nucleus, use glucose for energy, and have bigger ribosomes (80s)
The Eukarya domain.
The organisms can be divided into three domains, based on the type of cell that the organism is made of:

Bacteria domain: cells do not contain a nucleus.

Archaea: cells don't contain a nucleus and they have a different cell wall from bacteria.</span><span>
Eukarya: </span></span>They keep their genetic material inside the nucleus. Composed by animals, protists, plants and fungi
Answer:
The Hardy-Weinberg law states that in a sufficiently large population, in which matings occur randomly and that is not subject to mutation, selection or migration, gene and genotypic free frequencies are kept constant from one generation to another, once a state of equilibrium has been reached, which in autosomal loci is reached after one generation.
It is said that a population is in equilibrium when the alleles of the polymorphic systems maintain their frequency in the population throughout the generations.
