Each year, a penguin will molt its feathers. They do this to replace worn-out feathers as they grow. Give an example of another organism that does something similar.

Snakes molt when they grow, and their skin is small for them.

Explanation:

Snakes molt is also called shedding. When snakes grow, their skin does not grow with them so, they have to lose it to grow a new one for their increased size. This process involves some time, and the snake looks for rough surfaces to remove the skin. The final result is the removal of the old skin in one piece.
