Each microscopic pore is 20,000 times smaller than a water droplet, but 700 times larger than a water vapor molecule, resulting in a membrane that prevents water precipitation like rain and snow from penetrating through into your layers, but still allowing sweat vapor to escape. When combined ...

Why are sweat glands important? How does light pollution affect plants? Why are the products of the light reaction of photosynthesis important? What factors affect the rate of photosynthesis? Why is water a product of photosynthesis? How does salt affect evaporation?
