Answer:
Brain is composed of three main parts: cerebrum, cerebellum and brain-stem.
Stimulus interpretation and speech are controlled by cerebrum. It is the biggest part of brain and performs important functions.
While movement of muscles, walking and movement of tongue is controlled by cerebellum. It is present under cerebrum and performs functions associated with coordination.
Respiratory activities, hunger and other automatic functions of body are controlled by Brain-stem. It connects cerebrum and cerebellum to the spinal cord.
Overpopulation. Our population is rising fast and it is not very stoppable.
Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. The chemical equation is C6H12O6 + 6O2 → 6CO2 + 6H2O (glucose + oxygen -> carbon dioxide + water).
