Answer:
The thylakoid membrane is responsible for separation of different regions of the mitochondrion and the chloroplast.
This membrane is responsible for the major difference between chloroplasts and mitochondria in terms of their structure and function.
The membrane is very important in chloroplasts and it fills the role of the inner mitochondrial membrane in electron transport and the chemiosmotic generation of ATP.
External respiration (correct answer) involves the exchange of oxygen and carbon dioxide within the environment.
The exchange of wastes through the skin is just called excretion by sweating.
There is no exchange of nutrients that occur in the lungs but rather absorption of nutrients is the function of the gastrointestinal tract.
The exchange of oxygen and carbon dioxide within the cell is called cellular respiration and involves carrying oxygen from the blood to the cell then the cell uses it as the final electron acceptor in the electron transport chain. The metabolic wastes of the cell, primarily carbon dioxide, goes now to the bloodstream to be exchanged for oxygen in the lungs.
The answer is population I think
