Question

this is a random question, im not sure what subject it comes under, so i randomly put chemistry.but how exactly does a seashell get its various beautiful shapes, and its different designs?

Answer 1

Explanation:

Mantle tissue that is located under and in contact with the shell secretes proteins and mineral extracellularly to form the shell. Think of laying down steel (protein) and pouring concrete (mineral) over it. Thus, seashells grow from the bottom up, or by adding material at the margins.
