Explanation:
In a circular bacterial chromosome, the structure of DNA is a right-handed double helix In a circular bacterial chromosome.
If DNA is twisted in the right-handed direction, it becomes overwound. Overwinding results in positive supercoiling takes place. If DNA is twisted in the left handd direction, it becomes underwound. Underwinding results in negative supercoiling.
f. One effect negative supercoiling in bacterial chromosomes is to promote separation of the two strands of DNA in the double helix

Energy flow in the earth</h3>
The earth in itself is a massive ecosystem. Energy flows into the earth and out of it. The only source of energy input to the earth is the sun. Also, energy is lost from the earth via re-radiation of energy in the form of infrared rays.
However, this inflow and out flow of energy affects the temperature of the earth. A balance of this two process must be maintained in order to attain a constant earth temperature.
