Answer:
The average kinetic energy of the molecules is proportional to absolute temperature. At any given temperature, the molecules of all gases have the same average kinetic energy.
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. Solids, liquids and gases all expand when heat is added.
Because the surface of a leaf is smooth if the surface was rough the water would get stuck but it is smooth so the water just rolls off
Answer: Migration, because species move to other places for food or a better or more suitable habitat and sometimes their is other species there.

Answer:
DNA is made up of molecules called nucleotides. Each nucleotide contains a Sugar group, phosphate group, and a nitrogen base. The four type of nitrogen bases are thymine (T), cytosine (C), guanine (G), adenine (A). The order of these bases is what determine DNA.
