When you combine sodium and chloride together to make sodium chloride (table salt) you get a lot of bright light and a lot of heat. This type of reaction is called exothermic.
Answer:
1- A species can migrate over long distances because they have metabolisms suitable for that, adaptation mechanisms to withstand different adversities. They usually do it to be able to reproduce in ideal climaxes or feed on certain living things or plant species.
2-The existence of oil fields, or oil towers for the manufacture of fuel.
3-Implement electric cars or batteries that do not depend on fuels such as diesel, naphtha.

The bacterial genes are usually found in operons. Each operon comprises regulatory sequences of DNA that function as binding sites for regulatory proteins, which inhibit or encourage transcription. The regulatory proteins usually combine with small molecules that can make the protein inactive or active by altering its tendency to combine with DNA.
The four combinations of active or inactive regulatory proteins, which could be observed at any time in the cell are:
1. Active repressor, active activator,
2. Active repressor, inactive activator
3. Inactive repressor, active activator
4. Inactive repressor, inactive activator
