Explanation:
What animal are u talking about?
<span>Bacteria can be capsulated or non-capsulated. When it has no case, it is non-virulent.When it is capsulated, it is to a great degree destructive. The bacterial case is made of Glycocalyx - a sugar coat is efficient holds fast unequivocally to the bacterial cell layer such that no antigen or immune response can enter the bacterial cell film; permitting the microorganisms to a great degree harmful and deadly.</span>
1.) See how close the layer is to the surface of the earth. The closer it is, the younger it is.
