Question

Which comes first egg or hen give reason and why

Answer 1

Hi friend!!

#Hen came first because eggs are produced from hens.

#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.

Answer 2

Answer:

The egg

Explanation:

• Chickens would have evolved from a previously existing animal such as a dinosaur.
• Dinosuars lay eggs and chickens hatch from eggs so from thousands of generations of mutation, the chicken would have been formed.
• However, due to the chicken hatching from an egg, the chicken egg would have come first.
