3) Write 3 stages that both average and large stars go through in their life cycle. 2) Write 2 stages that a large star goes through but an average star does not (and explain)

1) Write the 1 factor that determines what stages a star goes through.

The heliocentric and the geocentric models of the solar system included these central principles

Give me a example of a decomposer. explain what would happen if decomposers were absent from a forest ecosystem

Materials will have different energies associated with the electrons inside them. this is related to how strongly bound they are by their work function. if we sandwich a material with a very low energy between two materials with a high energy, we create a trap for an electron. if this trap is very narrow in one direction in comparison to the others, this is approximately a 1-dimensional box that confines the electron. what is the lowest energy of an electron in the box if the thinnest direction across the materials is 4.81 nm?
