Epigenesis
Epigenesis is the concept that emphasizes development resulting from ongoing bidirectional exchanges between heredity and all levels of the environment.
Epigenesis is the development of organisms such as plants, animals and fungi from an egg, seed, or spore or egg through a series of phases in which unorganized cells differentiate into organs and organs systems. The theory of epigenesis which claimed that structures evolve during development that are not already preformed was created by the German physician C. F. Wolff in 1759.

Answer:
the trend that favor the more leaning curve from the explanation
The diagram given here describes the process - The alveolus is a part of the lung and assists with gas exchange. The goal is to get gases into and out of the cells, so they enter our body, go to our lungs and then diffuse into our blood and travel to our cells through our circulatory system.
The alveolus or alveoli are tiny air sacs which is a hollow cup-shaped cavity in the lung parenchyma. It functions as the respiratory unit. It helps in gaseous exchange to and from the lungs.
- The gaseous exchange takes place with these sacs.
- Diffusion is the process that takes place in this exchange
- In this process, oxygen moves from a high concentration area to a low concentration that is alveoli to blood capillaries and then circulates to various cells.
- In the case of carbon dioxide, it reaches near the blood capillaries near the alveoli where it diffuses into the lungs through alveoli.
Thus, the correct description is - The alveolus is a part of the lung and assists with gas exchange. The goal is to get gases into and out of the cells, so they enter our body, go to our lungs and then diffuse into our blood and travel to our cells through our circulatory system.
