The best explanation of the difference is <span>Skin color, a polygenic trait, is also determined by environmental factors.
Environmental factors can greatly impact somebody's skin and its pigmentation. In this case, the presence of sunlight is the environmental factor - one of the boys works in a movie theater, with little to no exposure to the Sun, whereas the other one spends most of his days in sunlight, which is why his skin color is different from his brother's.

Hello?? Can anyone help me??! PLEASE
kolezko [41]

Answer:

The temperature is staying the same. In the graph when it shows solid/liquid and liquid/gas, the temperature stays the same until it changes. This is because it reached it's melting point/vaporizing point. For example, a solid gets heated up, it then reaches it's melting point but it can't go higher than that because it isn't fully a liquid yet, once it's a liquid it will then continue to rise in temperature.

I don't think I put enough detail into that explanation but I hope this helps your problem.
