TRUE OR FALSE:

17) Glycogen is an example of a carbohydrate.

56) The cells of a true bacterial colony come from many originating bacteria.

57) Superoxide dismutase is an enzyme involved in oxygen detoxification.-

Explanation / Answer

35. Cell wall lipid is the answer. Acid fast stain is used to stain some bacteria which cannot be stained with the Gram staining procedure such as Mycobacteria. There cell membrane is very waxy contains Mycolic acid. Only Acid fast stain can cross this type of lipid rich membrane applying heat,

36. The Basal body is a part of Flagellum. Actually it is the base of the flagella where it is anchored inside the body.

37. Nucleotide with in the same strand of DNA is held together by phosphodiester bond.

38. Protein and necleic acid contains C,H,O,and N.

39.Here the questing is a major macromolecules of cell contains phosphorus. so your answer should be a single thing. Here the anser will be CELL MEMBRANE or membrane lipid. Cell membrane contains phospho lipids. Nucleic acids also contains phosphorus but membranes molecular wight is much larger than nucleic acid. so membrane contains much phosphorus.

17. Yes Glycogen is a carbohydrate. It actually stored in liver. It generates from glucose from a process called Glycogenesis.

56. yes, True bacterial colony comes from division or binary fission from the existing bacteria. A bactrial colony may from overnight. True bacteria are bacteria that contains rigid cell wall theyare able to photosynthesis or chemosynthesis.

57. True. Super oxide dis mutase prevents cell damage by harmful effects of oxygen.
