Document Summary

All life composed of cells which is basic unit of all life. Properties of life: consists of organized cells. Above properties are called emergent because they come about or emerge form many simpler interactions. All components of solar system were formed at the same time by gravitational condensation of matter preset in an interstellar cloud which consisted mostly of hydrogen. Intense heat and pressure generated in central region of cloud formed the. Sun and remaining dust and gas condensed in planets. Over time, heat on earth cooled, and solified in rock of the crust \approx. took. 500 million years for earth to cool to temperatures for life to be developed on planet. Earth is in a position unlike other planets that allows for life because heat from sub allows the surface temperatures to be within a range that allows water to exist in liquid state.
