Explanation:

Natural selection means the process of changing the adapting the new environment. Based on the given data one can conclude that the individual with thicker fur had a survival advantage in the cold environment.

Why natural selection occurs?

Natural selection takes place due to 3 underlying reasons:

Reproduction

Heredity

Variation in fitness of organisms.

Due to these reasons, natural selection can leads to speciation.

As the individual are living in cold environment, they need to adapt the change in environment. So, individuals with thicker fur had a survival advantage in the cold environment, allowing these individuals to reproduce more often and create more offsprings.

Thus, option C is correct.

N normal exhalation, the diaphragm and intercostal muscles relax to contract the chest, which creates a positive pressure. this
aliya0001 [1]

This is the passive type of process.

As the diaphragm relaxes, the pleural cavity contracts, which exerts pressure on the lungs. As a consequence, the volume of the lungs reduces and the air is passively pushed out of the lungs. Exhalation is passive, thanks to the elastic properties of the lungs.
