The species which are present on earth, they undergo the process of adaptation continuously and this adaptation is done to make a balance in their body and this balance is called as the homeostasis.
00:14
Homeostasis is also referred as a dynamic equilibrium that is attained by a particular species here.
00:22
The term dynamic denotes that the constant change which is given by the environment, it is being accepted and the, this constant change is being as soon as it gets accepted, the species tries to restore it to the normal set value and this is called as equilibrium.
00:40
Thus it is referred as dynamic equilibrium that is achieved by an species and this dynamic equilibrium is achieved using a set value or a point that is being referred as normal in a particular species and this is called as the set point.
00:57
This set point is naturally present in all of the species and this should not be altered at all.
01:05
Because when this particular set point is being altered, it can become very dangerous to the particular species because an abnormal value will be considered to be a set point and this in turn can put the species at risk and sometimes at death.
01:20
So the normal changes which are made by a body is called as an adaptation.
01:25
For example, let's say.
01:25
When a particular when in a very hot environment this hot environment can make a person sweat a lot and this sweating in turn will make will in turn will give lot amount of water outside the body hence the person is also made that that is the thirst center is also activated and this in turn makes the person consume water so the amount of water lost will be compensated for the amount of water consumed so this is how the body maintains the temperature differences between the external and then the internal environment.
02:04
And also when present in very cold places, having a thick work can help can help to retain the amount of heat present within the body.
02:13
And whereas when present in a very hot environment, having a thin coating of having a thin coating over the skin surface can help to radiate the maximum amount of heat to the external environment.
02:25
So these are.
02:26
Some of the adaptations which can be seen in species.
02:29
And when this particular set point, that is when a particular abnormality is continuously maintained by an organism, this abnormality will be when it is maintained for a prolonged period of time, this abnormality will be considered as a new set point and this new set point cannot be normally regulated...
