Hello!
The type of selection which is illustrated by these two graphs is a
Stabilizing Selection
Among the different types of Natural Selection.
Stabilizing Selection is the one that happened to the parrot population in the rainforest in Costa Rica. This is characterized by the selection against the extremes of an attribute and reinforcement of the mean, that's why this type of selection is also called Selection towards the mean.
In this case, there was selection against the parrots with colored feathers other than green that didn't help them to camouflage in the rainforest.
Have a nice day!

Answer:
The correct answer is D. Umbilical cord
Explanation:
The umbilical cord connects the fetus to the placenta and through it exchanges nutritional substances as well as oxygen-rich blood. The umbilical cord is maintained throughout gestation until the moment of birth, when it is cut and leaves a permanent scar, the navel. The umbilical cord is responsible for breathing and feeding the fetus until the moment it is born, so any failure or blockage in the circulation of oxygen and nutrients through the cord can lead to injury or even death of the embryo. It also serves to remove waste and carbon dioxide (CO2).
