What phases in the cell cycle come before meiosis?

G1 phase, S phase, G2 phase. At the end of the interphase, comes the miotic phase. This is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.

it creates acid rain

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
