Fast-moving cold fronts force the warm air ahead of them to rise more quickly than slow movers. The clouds and rain are mostly along the front or ahead of it, and heavy rain or thunderstorms are common. A slow-moving front lifts the warm air more gradually; the rain is less intense, and the clouds form along and *behind* the surface cold front.

Common examples of this would be if you place your hand in extremely warm or cold water, and an immediate response of pulling out of the water or any fluid, is an example of this extreme response, other responses are what is done in everyday, like being thirsty or hungry etc.
These behaviours are shared by all organisms even the most simple ones.
In Double Stranded DNA , Adenine pairs with Thymine as we know, it means amount of A = Amount of T. Here A=30% so T=30%
Total will be 100% (for all 4 bases) , left out is 30 % which will be equally divided by Guanine and Cytocine , hence G=20% and C=20%.
A=30% T=30% G=20% C=20%
