Environmental factors can influence the gene expression in some organisms. using a specific example, explain how a lighter shade of a color can affect the gene expression in an organism where lighter shading affects the phenotypes of the organism. first answer will mark as the brainliest

An example is the drop of white-colored moths and an increase in dark-colored moths in London after  the industrial revolution. Because darker-colored moths could camouflage well in the sooty environment (due to industrial emissions), they were preyed less by their predators. White-colored moths stood out and due to being preyed more their numbers declined over generations – because they wouldn’t survive long enough to reproduce and pass their genes to the next generation. The predominant color for the moths’ population became dark color.

to figure the total magnification of an image that you are viewing through the microscope is really quite simple. to get the total magnification take the power of the objective (4x, 10x, 40x) and multiply by the power of the eyepiece, (usually 10x)
