Answer No 6: The correct option is 1) the maintenance of homeostasis
Step-by-step explanation:
Homeostasis can be described as the process in which the internal conditions of an organism are maintained or kept at equilibrium, despite the changes in the external environment. The diagram is depicting the process by which the amounts of oxygen and other organic compounds are being maintained. And the removal or carbon dioxide and nitrogenous wastes also shows homeostasis is being maintained.
Answer No 7: Mitochondria

Mitochondria can be described as the organelle where the process of cellular respiration occurs. As we can see in the diagram, oxygen and organic material is being taken in and carbon dioxide is being released. Hence, this depicts that cellular respiration is occurring in the particular organelle.
