Question

When bones are done growing, they harden and the _________________ line becomes smaller

Answer 1

When bones are done growing, the epiphyseal line becomes smaller.

Step-by-step explanation:

When bones are done growing, they harden and the epiphyseal line becomes smaller. The epiphyseal line is the remnant of the epiphyseal plate, which is present in growing bones. As the bone matures, the epiphyseal plate is replaced by bone, resulting in the formation of the epiphyseal line.
