Answer:
Regulon
Explanation:
A regulon comprises of a group of operons that are controlled by the same regulatory protein referred to as a regulator which could act as a repressor or activator.
Regulons in bacterial cells are referred to as the fundamental unit of the response system. Regulons are majorly used when referring to prokaryotes that have their genome organized to operons, although this term is not limited to that. The genes that are found in a regulon are arranged into two or more operons at different regions on the chromosome.

Answer: Natural selection is one of the forces of evolution and the enviroment where the species lives is the selection agent. For example, suppose a mosquitoes population in a environment free from insecticides, in this environment there's a high frequency of non-resistant mosquitoes because the environment is not exerting any pressure on the resistence trait. But when the environment changes and we use a insecticide upon the mosquitoes population, the populations changes because the non-resistant ones die but those resistant survive and beggin to reproduce more effectively. That's natural selection, differences in survival and reproduction between individuals with different phenotypes (traits) and this differences depend of environmental changes.
