Answer 2

Hi friend!!

#Hen came first!

#Hens have a protein in their ovaries.

#The protein – called ovocledidin-17 (OC-17) – acts as a catalyst to speed up the development of the shell.

#Scientists used a computer to zoom in.

#It showed OC-17 was crucial in kick-starting crystallisation.

#The protein coverts calcium carbonate into calcite crystals which makes up the egg shell, creating six grammes of shell every 24 hours.
