Answer:
B, C, E, G
Explanation:
B - As particles are heated, they gain heat energy (or thermal energy, Q) from whatever the source may be.
C - Thermal energy particles gain is converted into kinetic, and the more KE/kinetic energy particles have, the more energy they have to move around.
E - When particles have more energy to move around more, they slide and move past each other and create more space; hence, they become further apart.
G - Eventually, particles will have enough energy and will move around so much that the attracting forces holding them together in the first place will be lesser than the particle's energy to break free and move from the attractive forces.

The element found in the liver that helps prevent anemia is iron.
Iron is an essential element for blood production. Close to 70% of the body's iron is found in the red blood cells. In the red blood cells it is a vital ingredient of hemoglobin, the red pigment that gives blood its red color. In the muscle cells, iron is found as myoglobin.
Iron is stored mostly in the liver as ferritin or hemosiderin.
When iron stores are finished or exhausted, the condition is called iron depletion. When the shortage of iron is severe, it results in a condition known as iron deficiency anemia whereby the red blood cells do not have enough hemoglobin.
