  • How does sweat cool you down?

    Q: How does sweat cool you down?

  • Q: What are some humorous facts about men's testicles?

    A: Testicles change size in order to stay at the correct temperature to produce sperm, explains WebMD. Consequently, when a man's body is cold, the brain delivers a message to the scrotum that causes the testicles to shrivel up and preserve heat. The opposite is also true: The brain sends a message to the scrotum when a man's body temperature is warm, which causes the testicles to enlarge and become more floppy so that the body can release heat.

  • Q: How do steroid hormones exert their action?

    A: Steroid hormones exert their action by initially entering a target cell's plasma membrane and then binding with specific receptors before translocating to the nucleus to initiate or alter the expression of a gene in the production of new proteins. These hormones are insoluble in water and require plasma carriers for transportation to their target sites, states the University of New Mexico.
