smooth muscle
Explanation:
Smooth muscles are found on the walls of alimentary canal, blood vessels and tubular visceral organs e.g., urino-genital system and respiratory tract. The cells that make up the smooth muscles are spindle-shaped each with a single nucleus that is centrally located.

Answer:
true!!
Explanation:
the faster molecules move, the warmer the object is. think of how much energy you feel when you touch hot water and you whip your hand back, thats similar to how the molecules are movin, all that heat is energy built up in them and theyre moving around all crazy haha. Then think of putting ice in the freezer, all the molecules are kinda frozen in place, all squished together, because they dont have enough energy to move around. so, when the hot molecules with all that energy are moving around, the food coloring is able to get all over in the water. Kind of like if youre on a road trip the faster you drive the faster you'll get places. if you drive super slow, then it'll take forever to get there. so true, when food coloring is dropped into faster hotter molecules, it will spread faster. :)
