Lamark believed in the inheritance of acquired characteristics. That is, that if an individual's body or organs changed in some way during the course of their life time (due to the environment or some other pressure), that these characteristics could be passed on to the next generation.
This was his theory of evolution. Therefore, if, slowly elephants started using their trunks to an advantage more, they would start to develop and grow. Lamark believed these acquired traits would be passed on to the next generation. We now know this not to be true, and random, selectively advantageous mutations in DNA are what cause evolution over time.
A scientific theory is a theory that explains the scientist's observations, whereas a scientific law is a repeated pattern in the world that we have not sought an explanation for.
Answer:
The correct answer is Jenga blocks.

A toy, which appears like the composition of a muscle is the Jenga blocks. In case if a piece is tried to be moved it disrupts the pieces that are present close to it, as well as the entire game. This may associate the muscles, which are tight by an individual, similarly to the game, the tight muscles can be associated with the overall stability of the individual.
