Question

what is equilibrium? a state where a population is evolving a state where species are dying out a state where things arent changing

Explanation:

Equilibrium refers to a state of balance or stability. In various scientific and non - scientific contexts, it implies that there is no net change occurring. For example, in a chemical reaction at equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction, and there is no overall change in the concentrations of reactants and products. In a biological population, if it is in equilibrium, there is no significant evolution (no change in allele frequencies due to evolutionary forces like mutation, migration, selection, and genetic drift) or no net change in population size due to balanced birth and death rates. The first option “a state where a population is evolving” is incorrect because evolution implies change. The second option “a state where species are dying out” also implies change (a negative change in species numbers). The third option “a state where things aren't changing” aligns with the general concept of equilibrium.

Answer:

a state where things aren't changing
