Answer:

Paleontologists

Paleontologists use fossil remains to understand different aspects of extinct and living organisms. Individual fossils may contain information about an organism's life and environment. Much like the rings of a tree, for example, each ring on the surface of an oyster shell denotes one year of its life.

Answer:

c. provide rigidity of the wall

Explanation:

Secondary cell walls contain additional components, such as lignin, which is hard and occupies the interstices between the other components, making the walls rigid and permanent.
