Natural selection is a theory developed by Charles Darwin. It is believed that animal species evolve by nature "selecting" the ones that are fit to live in specific environments. For example, if an animal lacks a trait that is needed for a certain environment, it is likely to die. The animals that have the needed traits are more likely to live and procreate, which will pass on the trait to its offspring. Hope this helped!
Answer:
These gel cubes can be thought of as representing individual cells. As the cubes interact with their surroundings based on the amount of surface area and volume they have, the efficiency movement of substances in and out of cells depends on the two attributes as well. Greater surface area will mean more efficient rates of diffusion, which implies a smaller surface area to volume ratio is ideal for a biological cell.
Hope that answers the question, have a great day!
