Describe in general the structure and interior density, pressure, and temperature conditions of an average star such as the sun. $($Select all that apply.$)$

convection zone

This region is the final tenth of the way to the star's surface.This region is located about one quarter to about nine$-$tenths the way to the surface of the star.This region is located at the center of a star and extending about one quarter of the distance to the surface of the star.It has about the density of water.Gases at the boundary between this region and the region below it are heated, rise to the surface, and radiate away the energy.The cooler gases contract and fall.This region has density of about twelve times that of solid lead.The temperature is about $5500$C$.$This region contains about half the mass of the star.It absorbs and re$-$radiates energy from the region below it$.$The temperature is about $15$ million degrees Celsius.This region is not very dense$-$only about $1$ percent the density of water.This region has a pressure of about $300$ billion atmospheres.
