Which fat is mostly likely a solid at room temperature?
A) one that is saturated
B) one that is unsaturated
C) one with double bonds
D) one that contains no hydrogen

Saturated fat is typically solid at room temperature.

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.
