Answer: The lower areas of the Atmosphere have a high temperature through the heats from the ground.
Explanation: High temperature experienced on the Earth surface is majorly caused by heats from the ground ( Earth crust).As a person ascend up to the Toposphere the temperature continues to reduce because because the heat from the ground is reduced as the heights increased.
It has been proven that as a person ascends into the Toposphere the amount of air and pressure reduces this will eventually lead to expansion of the gas particles which will then reduce the temperature.
The mitochondria is the powerhouse of the cell because it takes nutrients and breaks it down to provide energy for the cell.
Energy comes from the Sun, plants and animals that we eat, to provide us with nutrients we need for energy.
