Arthropods periodically shed and discard their exoskeletons as they grow in a process called
a. segmentation.
b. molting.
c. reproduction.
d. metamorphosis.

Letter B

Explanation:

  Moulting or ecdysis is a process that occurs in arthropods and is characterized by changing the skeleton of these animals to ensure their growth. This process is essential because these invertebrates have an external skeleton, which makes continuous growth impossible and for this reason this animals need to change its skeleton and to produce another new one.

  Despite being rigid, the animal gets its movement thanks to the joints. Because of this property, the phylum was named Arthropoda, which means “articulated feet”. The interesting thing is that you can see these periodic seedlings scattered in the environment, like and "bark".
