Choose ALL the correct reasons that the outer
planets are larger than the inner planets:

1. The planets grew massive enough to attract light
gases into their atmospheres

2. There was more material in the outer part of the
ring for planets to build themselves from

3. Ice could solidity beyond the frost line, offering up
more mass to the planets to acquire

4. The gravitational constant was different for outer
planets

They are all in a iving organism.

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
