Answer:
Bronchial pneumonia
Explanation:
The secondary infection is caused during the treatment for any infection or after the treatment. The changes in the immune system is a cause of this infection.

Correct answer: C) Only in a narrow range of temperature and pH
Homeostasis is defined as the ability of the body to regulate temperature and internal conditions even when there is a change in the external environment. Homeostasis is important for the survival of life because the cells of all the organism can function well only in a limited range of temperature and pH.
All the cells of the body use enzymes for proper function, and the enzymes can only function under a limited range of temperature and pH. In extreme conditions of cold or heat enzymes will not be able to function properly and lead to the death of the cell.
