Answer:
the first is mostly false but somewhat tru the second is true and the third is true
Explanation:
I'd say thermal energy. I say that because if I remember correctly the Second law of thermodynamics describes the energy in this case the boiling water (heat) to areas that are not hot like the ice cube. With heat energy we deal with warm moving to the an area of cold. The molecules in the ice cube from what I remember in college aren't moving at all hence the block of ice but when heat is added to the ice cube then the molecules in the ice cube start moving and getting excited, which causes the ice cube to start melting, as my bio teacher in college said.
Hopefully this helped and good luck.
The answer would be mitosis.
I remember the mitochondria breaking down sugars to create energy.
