Answer:
I agree most with Natalie. Particles in a gas are very high energy/move around a lot, and well separated. Meanwhile, liquids particles don't move as much as the gas particles do, but still have considerable movement and are closer together. Finally, solids are composed of particles that are tightly packed together and move the least out of the three states.
Hope this helps!

Catabolism together with anabolism is a part of metabolism. It is the set of metabolic pathways in which the molecules are broken down into smaller units and the energy is released. Released energy of catabolism (in a form of ATP) is used for the maintenance and growth of cells. Examples of catabolic processes are glycolysis, the citric acid cycle or degradation of macromolecules: proteins into amino acids, lipids into free fatty acids...
So, the endoplasmic reticulum does many things, such as folding the protein molecules in sacs called cisternae. It also transports synthesized proteins in vesicles to the Golgi apparatus.
I think it would be the option "C"
