Answer:
I will give a hypothesis. Just like a tree, when you cut a tree by its trunk, you will the rings. The rings around it represents the tree's age. So when you cut rock, the pores in the rock determine whether it is an old rock or a fossil rock.
Explanation:

Explanation:
Eukaryotic cells have the nucleus enclosed within the nuclear membrane.
The cell has mitochondria.
Flagella and cilia are the locomotory organs in a eukaryotic cell.
A cell wall is the outermost layer of the eukaryotic cells.
The cells divide by a process called mitosis.
These animals were living in an environment with a warm climate that results in changing sea levels. These conditions create a lot of shallow inland seas allowing these animals to thrive. The Cretaceous period is the last period of the Mesozoic area where new groups of mammals, birds, and flowering plants appeared on Earth.
