According to the theory of evolution, it works like this:
Every once in a while, an organism develops (having genes slightly different from its parents) that's different from its parents.
If that difference is helpful to the survival of that organism or its children, which is very unusual, then that organism is likely to have more surviving offspring than others. It is said to be favored for survival.
Over the course of many generations, we assume that the variation that increases surviving offspring will come to be the dominant (regular) characteristic in the population.
Remember: evolution only happens to populations, not to individuals (except in fiction).
adaptation or natural seclection ethier one is the right one
Adaptation
Natural selection creates a stronger species that is able to live longer and produce more. It continues to work because after a few generations, the traits will become common in the population.

I believe it to be the Balmer Series.
biasing resistor is important because the voltage passing through it will limit the current and derive the next device, i.e. transistor etc. when a signal is applied to this circuit, biasing resistor helps to signify that signal and as a result we can examine our output.
7400 series parts are for consumer electronics. 5400 series parts are for military applications. The 5400 series parts tolerate a wider supply voltage, work in wider temperature ranges, and have better noise immunity. They are also vastly more expensive. :)

Expalain the difference between cyclical and seasonal variations in a data series?
yea they are
The irregular, unsystematic and unpredictable variations caused by some unusual events such as floods, strikes, wars, earthquakes and fires etc. are called residual variations. these variations are also known as accidental, irregular or erratic variations.
Cyclical variation : cyclical variations are recurrent variations in a time series usually last longer than a year. Most of the time series in business and Economics show such cyclical variation. A business cycle has four wheel defined periods : prosperity, decline, depression and improvement.
What series/ year? There are many variations.
