Explanation:
Living things are adapted to the habitat they live in. This is because they have special features that help them to survive. The development of these special features is the result of evolution due to gene mutation. These mutations aid in the survival and reproduction and passes on from one generation to the other.
Answer:
1. Sympathetic
2. Parasympathetic
Explanation:
The sympathetic nervous system is activated when the person experiences any stress conditions. This nervous system stimulates the release of stress hormones from the adrenal gland and generates flight or fight response. There are an increased heart rate and breathing rate to increase the oxygen supply to skeletal muscles.
Once the person comes out of the stress conditions, the parasympathetic nervous system is activated which slows down the physiological responses generated by the sympathetic system. The activated parasympathetic nervous system stimulates the digestion and absorption of nutrients.
