Which of the following are two reasons why the outer planets are comprised of more gas than the inner planets? they are smaller and located farther away from solar radiation. they were formed near radiation and they are smaller. they are further away from solar radiation and they are larger. they are larger and they are bombarded by radiation.

They are further away from solar radiation and they are larger.

Explanation:

The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous. As the gasescoalesced to form a protosun, the temperature in the solar system rose. In the inner solar system temperatures were as high as 2000 K, while in the outer solar system it was as cool as 50 K.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
