Answer:
The correct answer is -
1. right-handed
2. right-handed
3. positive
4. left-handed
5. negative
6. negative
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

<h2>Further Explanation
</h2>
The ability of cells to communicate, that is, receiving and sending signals from and to other cells, determines the interaction between unicellular organisms and regulates the function and development of the body of multicellular organisms. For example, bacteria communicate with each other in the quorum sensing process to determine whether they are sufficient before forming biofilms, while cells in animal embryos communicate to coordinate the process of differentiation into various cell types.

Plants produce oxygen and glucose as a result of photosynthesis
When grapes are soaked in water, the grapes then swell up because grape's cells have a high concentration of solutes in comparison to the water. In other words, grapes have low concentration of solvent (that is water molecules ) in comparison to the concentration of solvent in water. In this situation, there will happen a process known as osmosis in which water molecules moves from a region of concentration of water to a region of low concentration of water through a semipermeable membrane. (the cell membrane of the grape's cell is also semipermeable,which only allows solvent molecules to pass through it)
