<reasoning>

Identify epidermal layer for cell division

The stratum basale (basal layer) is the deepest layer of the epidermis and contains actively dividing stem cells that continuously produce new keratinocytes to replace shed outer cells.

Identify sweat gland for thermoregulation

Eccrine sweat glands are distributed across almost the entire body and secrete a watery fluid directly onto the skin surface to cool the body through evaporation.
