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.
Because, photoautotrophs serves as their carbon sources.
Chemoheterotrophic bacteria are those bacteria that are incapable of producing their own food, they depend on photoautotrophs, which are capable of making their own food by trapping energy from the sun. Thus, photoautotrophs serves as source of food for the chemoheterotrophic bacteria.
There would be increase in oxytocin in one's cerebrospinal fluid in the brain causing a major role in the mother's behavior. Breastfeeding would release the oxytocin from the mother's brain.

The moon has a higher maximum surface temperature compared to Earth (253 degrees of moon to 136 degrees of Earth), but this also depends on night (which is colder) or day (which is hotter).
The moon has such extreme temperatures because it has no atmosphere that can "reflect" some of the heat from the sun, whereas the earth does.
