Answer 1

1. The right answer is response.

Response (or adaptation) can be defined in a general way as the functional adjustment of the living being in the middle, and, in particular, as the appropriation of the organ to its function.

Adaptation is the bringing together of a living organism with the external conditions. It perfects its organs, makes them more apt to the role they seem to play in the life of the individual. It puts the whole organism in coherence with the environment.

Heredity is the transmission, within a living species or a cell line, of characteristics from one generation to the next. The mechanisms of heredity are at the heart of the theory of evolution because they allow the accumulation of variations over generations that leads to the appearance of new species.
