I think the answer for this is D. Cuze panic and nervousness is definitely a trait of anxiety. Panic can be too cause of worrying to much can lead to it. D doesn't sound right cause passive behavior by diffinition would be that when someone is resisting or refusing to do what they are told or just trying to make someone really upset. Hope this works.
All living organisms carried out metabolism. Metabolism refers to a set of biochemical reactions on which the survival of the living organisms depend. Living organisms get energy from the food they eat to fuel the biochemical reactions. The majority of the energy needed in the body is derived from carbohydrates. When carbohydrate is eaten, it is broken down through the metabolic process of glycolysis and subsequent biochemical reactions and the final product is energy. This energy is then used for various purposes in the cell, especially to drive biochemical reactions and it can be transferred from one form to another.<span />

Well, I'm not sure about how many cells we have, but the average human body makes about 259 billion red blood cells per day. (That's why I don't know). Also, there are about 200 different types of cells with about 20 different types of organelles.
Hope this helps!
