Which statements describe how stars are born? Check all that apply.Stars are born in clouds of gas and dust called nebulas.The gas and dust are pulled together by gravity.If the cloud that is pulled together has enough mass, a red giant is formed.The pulled-together cloud collapses and becomes hot and dense.Heat and pressure cause nuclear fusion, which signals the birth of a star.
