Question

a characteristic of a nebula is that it-
forms halfway through a stars life cycle is at the center of the solar system has the coolest temperature in space is a region where stars are born

Explanation:

A nebula is a large cloud of gas and dust in space. Stars form from the gravitational collapse of parts of a nebula. The Sun, for example, formed from a nebula. The first option is incorrect as nebulae are where stars begin, not halfway through a star's life cycle. The second option is wrong because the Sun is at the center of our solar system, not a nebula. The third option is incorrect as there are colder regions in space (like some parts of interstellar space far from any heat source). The fourth option is correct as nebulae are stellar nurseries.

Answer:

is a region where stars are born
