Provide a brief answer for the question below:
Why are variations advantageous for the survival of a species but not always for an individual organism?
a. Variation is not beneficial to species rather than individuals because climatic changes do not always have drastic effects on the species, making survival difficult.
b. A bacterial population has established environmental harmony in temperate water. If the temperature of the water rises due to global warming, the bacteria will die. Only those who have adapted to the heat will survive.
c. Variation helps ensure the long-term survival of a species.
