Answer:
C) II and III only
Explanation:
Option 1 is not an example of phenotypic plasticity because each person is born with their own blood type and this doesn't change based on their environment and behavior.
Option 2 is an example of phenotypic plasticity because a person's red blood cell counts can increase based on their environment, i.e. moving to Denver, CO from Death Valley, CA. The higher elevation and decreased oxygen causes your body to produce more red blood cells.
Option 3 is an example of phenotypic plasticity because one twin can be taller than another because of differing behaviors, environments, etc.
Answer:
Dark colored moth
Explanation:
Moths either dark or light live on the bark of the trees. During industrial revolution in England, excessive pollution caused the darkening of bark of trees. Due to this environmental change, some of the light colored moths evolved and turned into dark colored moths. Both bark and moth being dark in color, made the moths untraceable by their predators. While the light colored moths on dark trees were easily recognizable by their predators.
Hence, the dark colored moths possess high fitness.
