How does a new hypothesis replace an older explanation of something in the natural world? To understand this let us look at one of the classical example of geocentric theory and heliocentric theory. The geocentric theory states the Earth is at the centre of the solar system and the Sun, Moon, and all the other planets revolve around it. This ancient theory failed to explain the phenomenon like the phases of Moon, solar eclipse and lunar eclipse. The modern heliocentric theory which states that the Sun is at the centre of solar system, and all the planets including the Earth revolve around it. This theory was able to explain all the phenomenons unlike the geocentric theory. Hence the heliocentric theory replaced the geocentric theory.

The autonomic nervous system helps in regulating some processes which are without a person’s conscious effort. Some of these processes are breathing rate, blood pressure. The autonomic nervous system is divided into two parts- sympathetic and parasympathetic. In general, the sympathetic part prepares the body for an emergency situations such as sight or flight, whereas, the parasympathetic controls body process during normal situations.
Sympathetic part is at work in these situations:
- Ross feels nervous because he misplaced his important work documents.
- Dory sees a bear while hiking in the woods, and her heart rate increases.
- Rodrigo’s breathing increases when he hears a scary sound.

- Maya feels her heart rate slow down after strenuous exercising.
- Sofia’s muscles relax when she finds her missing cell phone.
- Lisa feels calm after yoga class.
