Question 17 • * SY2025-26 - 2002070 M/J Comprehensive Science 2 Sem 1 CR

Which is an example of an environmental influence that would most likely result in natural selection?

Answer
A
The soil in a field always has lots of nutrients, so corn plants in a population can grow quickly.
B
A fish is born with a genetic mutation that produces a longer tail, allowing the fish to swim faster than others in the population.
C
A food resource disappears in a pond, and some frogs in a population can eat the remaining food resource, while others cannot.
D
The temperature in a lake remains constant, so most of the turtle population survives to adulthood.

Explanation

Natural selection is most likely when an environmental change gives some individuals a survival or reproductive advantage over others. When the pond’s food resource disappears, frogs that can eat the remaining food can survive better than frogs that cannot. The other choices describe stable conditions or a genetic mutation rather than an environmental change that favors some individuals.
