Mycobacterium tuberculosis (Mtb) is a bacterial pathogen that can cause skin infections as well as pneumonia. Mtb is often phagocytosed by immune cells called macrophages that normally destroy bacterial pathogens, but Mtb is somehow able to prevent the maturation of phagosomes into phagolysosomes, and to live and replicate inside these organelles. Which of the following differences would you expect contribute to the survival of a bacterium within an Mtb-containing phagosome, compared to a phagolysosome? (select two answers)

It mututates

Explanation:

It changes it form thus becomes resistant to phagocytes

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
