Answer:
Obligate anaerobes (Ans. D)
Explanation:
Gas gangrene is a bacterial infection which produces tissue gas in gangrene. This is caused by bacteria <em>Clostridium perfringens</em><em>. Clostridium perfringens</em> is a gram-positive, obligate anaerobic bacterium of the <em>Clostridium</em> genus. It is found in environmental sources & commonly found in raw meat and poultry.
Tetanus is a bacterial disease infected by <em>Clostridium tetani</em>, is an obligate anaerobic spore-forming bacteria. It is found in soil, dust and intestinal tracts of animals. Transmission of tetanus is commonly by contaminated wounds.
Answer:
Extensive damage to oligodendrocytes in the cns could result in l<u>oss of sensation and motor control.</u>
Explanation:
Oligodendrocytes are presnt in glial cells of Central nervous System which comprises of Brain and spinal cord.They are related to the nerve cells. It provides support by production of glial cell line derived neutrophic factor (GDNF) and brain derived neurotrophic factor (BDNF) or insulin growth factor IGF-1 they reduce ion leakage and decrease the capacitance of the cell membrane. Due to intensive damage of the Oligodendrocytes the motor nerves and other nerves of CNS damages looses it activity.
These are mainly occurred due to peripheral injury or demylinated diseases like multiple sclerosis, leukodystrophies,cerebral plasy and other congential disorders.Some chemicals like fluorouracil causes damage to the oligodendrocytes.

Answer:
All cells contain a nucleus and a nuclear envelope and the liver cell is no exception. It has exactly the same control over the cell as the palisade nucleus does. To keep it all together, it is surrounded by a cell membrane. This semi-permeable matter allows information to be spread from cell to cell.
