PLEASE HELP Answer both of them please! How do factors such as landforms affect weather patterns? Why do some air masses start as Maritime Tropical and later become Continental Tropical as they move across the United States?

its probably to later but whats the question

density and pressure

i took a test for bio that had this question and these were the correct answers, not sure if this is any now lol

the nervous system and the muscular system work together.  

sweat reaches the surface of the skin and evaporates into the air.

muscles underneath the skin relax, causing hair on the skin to lay flat.
