Normal development of the immune response is due in part to hormones produced by the

The immune response is the body's defense mechanism against the pathogens. The immune response of the body protects it from bacteria, viruses and multiple other disease causing organisms. The normal development of this protective immune response of the body is produced by as a result of the hormones which are produced by the thymus gland. The thymus gland produces the T-lymphocytes, which are important for a healthy immune response. The thymus gland secretes thymosin which is crucial for the development of these cells.

Hence, the answer is 'thymus gland'.

mitosis

Explanation:

The cellular process that enables the cells to grow and develop into tissue is mitosis.

Mitosis involves the division of the vegetative cells of the body and is important for the growth and development of organisms as well as in the healing of wounds or the replacement of damaged cells/tissues.

Hence, in treating burns and other types of skin injuries, the cells of the skin are stimulated to divide rapidly by mitosis so as to replace the damaged cells due to the injury. By doing so, the injured area heals.
