1 a toxic protein that stays inside the bacterial cell
2 a toxic protein that is excreted into the medium
3 lipopolysaccharide located on the surface of the bacteria
4 None of the above
Explanation:
Bacteria secretes toxins which is divided into two category :- (i) Endotoxin (ii) Exotoxin. - Endotoxins are membrane compounds of gramnegative bacteria which elicit an inflammatory response in host. - Exotoxins are secretes proteins which act locally and at distance of bacterial colonization site.

Tuberculosis is caused by
1 Mycobacterium sp.
2 Aspergillus sp.
3 Clostridium sp.
4 Vibrio sp.
Explanation:
Tuberculosis is a bacterial disease caused by bacteria Mycobacterium tuberculosis. - Bacteria usually attack the lungs but T.B. bacteria can attack any part of the body such as kidney, brain etc. - It is spread from one person to the other through the air, people who have active Tuberculosis in their lungs.

Bacteriophages kill
1 fungi
2 parasites
3 bacteria
4 viruses
Explanation:
Bacteriophages are viruses that kill bacteria. Bacteriophages are composed of protiens that encapsulate a DNA or RNA genome and may have structure that are either simple or elaborate. - Bacteriophages are so small they do not even have a single cell, but are instead just a piece of DNA surrounded by a protein coat. When they attack a bacterium, bacteriophages can multiply very quickly until the bacterium bursts and releases lots of new phages.

Bacteria with single flagella at one end is called:
1 monotrichous
2 lophotrichous
3 amphitrichous
4 peritrichous
Explanation:
Bacteria with single flagella at one end is called monotrichous. - Bacterial flagella are a coiled thread like structure sharp bent consisting of a rotary motor of its base and are composed of the flagellin protein.
