Question

what is the main function of sebaceous (oil) glands in the skin? to produce sweat to regulate body temperature to prevent water loss to secrete ear wax

Explanation:

Sebaceous glands secrete sebum. Sebum forms a protective layer on the skin. This layer helps reduce water evaporation from the skin, thus preventing water loss. Sweat glands produce sweat (eliminating the first option). Body temperature regulation is mainly by sweat evaporation (eliminating the second option). Ear wax is secreted by ceruminous glands (eliminating the fourth option).

Answer:

To prevent water loss
