Explanation / Answer

27. B. to stabilize cell walls.

sodium ions maintain the osmolarity of the cells and keep the cell walls intact. when they are transferred to normal water, they immediately lyse due to less osmolarity.

28. B. to stabilize the cell walls.

29. D. any of these.

In general, they belong to archae bacteria, but there are some archaebacteria even in eukaryota.

30. A

bacteriorhodosin is in the membrane of ETS

31. C. oxidative phosphorylation.

32. D. all of the above.

some bacteria reduce it to elemental mercury. some are able resist it. some convert it to volatie form.

33. B.

Chisso company in Minimata started releasing its waste into sea water without knowledge of presence of mercury. the side reactions in the factory produced methylmercury, a toxic form.
