During the warm temperatures of summer, the arctic fox produces enzymes that cause its fur to become reddish-brown. during the cold temperatures of winter, these enzymes do not function. as a result, the fox has a white coat that blends into the snowy background. what explains this change in color?
the genes of a fox are made of unstable dna
mutations can be caused by temperature extremes
random alteration of dna can occur on certain chromosomes
the expression of certain genes is affected by temperature

the expression of certain genes is affected by temperature

Explanation:

For organisms to survive changing environmental conditions, a lot of molecular processes occur in the genes.

For the arctic fox, enzymes coded by specific genes are periodically "switched on or off" depending on the temperature.

Thus, the change in colour can be EXPLAINED by the expression of certain genes affected by temperature

you did not attach the discourse, but i assume it to be the discourse on the origin and basis of inequality among men (the original titile in french is: "discours sur l'origine et les fondements de l'inégalité parmi les hommes"), also know as "second discourse". in this discourse, jean-jacques rousseau emphasizes that private property is the basis of all inequalities.

therefore, what enabled the old regime to maintain as long as it did was private property.
