.E nuclear membrane PE phospholipids 4. Bacteria have a cell wall so they can survive in: a an isotonic environment. b a hypotonic environment. c. a hypertonic environment. d. a dry environment. 5. An acronymometer can tell you if bacteria have LPS. You could use this device to tell you if bacteria were: a. Gram negative or Gram positive. b. round or rod-shaped bacteria. c. viable or non-viable bacteria. d. pathogenic or harmless bacteria. 6. Bacteria sometimes make and secrete digestive enzymes like amylase to break down extracellular polymers like starch. For Gram negative bacteria, the secreted amylase is found a. in the cytoplasm b. in the periplasmic space c. in the outer membrane interzone d. in the world outside the cellExplanation / Answer
4. Bacterial cell wall provide rigid limit and don't allow rupturing of cell placed in hypotonic solution. Hence option B is correct .
5. It will differentiate the pathogenic and harmless bacteria as the bacteria having LPS are having O antigen associated with them. Hence option D is correct.
6. Mainly amylase secreating bacteria are Bascillus sp. And secreted amylases are endoacting extracellular. Hence option D is correct .
