Survival of at least a few members of a population after a major environmental change is most dependent on
1) the population having an individual that is adapted to the original environment 2) the population having an individual that is adapted to great changes in the temperature and its environment
3) variations in many different traits in many individuals in the population
4) no variations in the color of the fur, skin, or feathers of the individuals in the population

Option B, the population having an individual that is adapted to great changes in the temperature and its environment

Explanation:

According to the Darwin’s theory “ the survival of the fittest” , any organism would survive through the process of natural selection by  adapting itself  to the changing environment in order to become the fittest among all of its native species.  

Thus, in order to survive even after some major environmental changes, an organism is required to adapt to the new conditions.  

Hence, option 2 is the correct answer which talks about adaptation as per the changing environmental condition

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme
