Peppered moths come in two colors, black and white. what did kettlewell show, with regard to peppered moth populations and tree coloring? (recall that england at the time was heated mainly by coal in urban areas.) a) in smoggy areas, dark moths have a higher survival rate than white moths. b) white moths stand out in rural areas, and quickly disappear from those areas. c) the black moth and white moth forms were actually two different species of moths. d) environmental conditions do not affect physical features of a species over a short time period.

Answer is: A) In smoggy areas, dark moths have a higher survival rate than white moths.

The light moths will be captured by predators more easily than the dark moths, and the population of dark moths will rise.

This is example of natural selection and adaptation.

Predators will easily capture white moths and their population will drope.

Moth populations can survive in a variety of different situations, because the environment is constantly changing and different alleles are favored.
