In humans, the hormone testosterone enters cells and binds to specific proteins, which in turn bind to specific sites on the cel
Crank

Answer:

They act to regulate the expression of specific genes (androgen-responsive)

Explanation:

Testosterone is a reproductive hormone in male humans. Testosterone as well as its closely related hormones e.g dihydrotestosterone, all belong to a class of hormones called "Androgens".

Androgens operate by entering into a cell and binds with specific androgen-receptor proteins (AR proteins). This contact activates the AR proteins, forming an androgen-receptor complex.

This complex then translocates into the nucleus of specific cells to bind to the DNA. Once it binds, it either inhibits or promotes the expression of specific genes (androgen-responsive). Hence, AR proteins are transcription factors because they play a significant role in regulating transcription of specific genes i.e. turning 'on' or 'off' of specific genes.

This process helps to direct the development of male sexual characteristics.

How does sweating assist in thermoregulation
Burka [1]
Sweating cools us down in two ways. Firstly sweat is wet so it cools down your body. Secondly, it evaporates which takes away some of our body heat. We sweat when we're hot and it helps to bring our internal temperature levels lower when it gets too high on a hot day, therefore assisting in thermoregulation.
