According to the evolution theory all living species are evolved from a simple life source with the passage of time.
Points of natural selection:
- Genetic variation are passed from generation to generation but environment can cause variations too.
- Individuals in species have gene variation which is due to random mutation
- Those who can not adopt to environment can not have their genes pass to next generation.
- Natural Selection is also called as "Survival of the fittest".
The response of the body's homeostatic control systems to large increases in muscle O₂ requirements during heavy exercise is the increase in body's pulmonary ventilation.
Homeostasis is the state of balanced internal system of the body. A homeostatic body does gets affected by the outer environment as it adjusts itself accordingly. The state of homeostasis can be in terms of thermoregulation, blood glucose regulation, osmoregulation, etc.
Pulmonary ventilation is the process of inhalation and exhalation of air. This is done to fulfil the demand of oxygen in the body and also to remove the waste carbon dioxide from the body. Pulmonary ventilation in simple terms is breathing.

The main property of water that helps sustain life on earth is that water has. a high specific heat. This causes water to gain heat very slowly.
Specific heat is the amount of heat required to raise the temperature of water by one degree Celsius. Specific heat of water is 4, 186 joules /gram Celsius, and it is higher than that of a metal and of any other common substance.
Due to this, water resists tendency to evaporate or to vaporize and therefore plays the crucial role of stabilizing temperatures on earth for terrestrial life and at the same time enabling aquatic organisms to maintain relatively constant internal temperatures.
