d. growth of primordial follicles

Answer 1

1. The process of the opsonization of the antigen particles involves option c. coating bacteria with antibodies or complement components.

Opsonization is the process of identifying the invading antigens by the use of opsonins.

2. Under resting conditions, most of the heat loss from the body occurs through option b. sweating.

Sweating is a process that helps in the regulation of body temperature with the help of sweat glands present in the skin.

3. In the female reproductive cycle, the surge of luteinizing (LH) hormone leads to option a. ovulation.

Luteinizing hormone stimulates egg release i.e. ovulation. It occurs 16-32 hrs after the surge begins.
