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>
Regulation of HMG-CoA reductase is termed as the rate of controlling enzyme of the mevalonate pathway which produces other isoprenoid and cholesterol.
The regulation of cholesterol is done by regulating the rate which determines step catalyzed by HGM -CoA reductase.
There is long-term and short-term regulation where HGM-CoA is inhibited by phosphorylation and catalyzed of proteins. There is regulated proteolysis of HGM-CoA reductase where degradation of HMG-CoA reductase by oxidized derivatives of cholesterol.
