The answer is <span>a. most living organisms can survive in environments with several different temperature and salinity levels.
</span>Aquatic plants and animals depend on dissolved oxygen for respiration. The other abiotic factors that impact their life in an aquatic ecosystem are temperature, salinity, and flow and they determine the quality of their life. <u>It is not true that most living organisms can survive in environments with several different temperature and salinity levels.</u> On the contrary, a few species can live in <span>environments with several different temperature and salinity levels, for example, some bacteria. The most organism can survive in a specific range of abiotic factors.</span>

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
