Answer to Question 1

FALSE

Answer to Question 2

Galaxies come in a wide variety of shapes and sizes. Protogalactic clouds that had low angular momentum may have formed halo stellar systems (elliptical galaxies), while clouds with higher angular momentum would have collapsed to a more disklike form (spiral galaxies). Such differences in the initial conditions is an example of the role of nature in galaxy evolution. An example of nurture is a collision between two spiral galaxies that randomizes the ordered stellar orbits, compresses the gas and causes it to rapidly form stars, eventually producing a gas-free, elliptical galaxy.

Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
