Question

for natural selection to occur, there must be genetic diversity and a selective pressure. select the statements that include examples of selective pressure. □ low light conditions on a forest floor favor plants with broad leaves that can absorb more sunlight. □ over many generations, the percent of darkly - colored pepper moths increases to 90%. □ a genetic mutation introduces albinism in a population of squirrels. □ a rise in average temperature increases the reproductive success of salmon that migrate earlier in the spring. □ barn owls prey on field mice that are easier to see due to their light coloring.

Explanation:

Selective pressure is an environmental factor that affects the survival and reproduction of organisms. Low - light favoring broad - leafed plants, temperature affecting salmon reproduction, and owls preying on light - colored mice are examples of environmental factors acting as selective pressures. The increase in dark - colored moths is a result of selective pressure, not the pressure itself, and a genetic mutation is not selective pressure.

Answer:

Low light conditions on a forest floor favor plants with broad leaves that can absorb more sunlight.
A rise in average temperature increases the reproductive success of salmon that migrate earlier in the spring.
Barn owls prey on field mice that are easier to see due to their light coloring.
