Both Jenny and Jack are correct.
Explanation:
According to the principle of superposition, both Jenny and Jack are perfectly correct.
The principle of superposition states that the oldest bed is at the bottom and the youngest is on top in an undeformed sequence of rock strata.
From this principle we can see that the sequence of the bed is:
- soil Youngest rock layer
- loam
- sand and gravel
- loam
- clay
- impermeable rock (limestone) Oldest rock layer
We can see that truly the clay is older than the sand and gravel according to Jenny.
The limestone is also older than loam according to Jack.

Some activated b cells will move to the follicles where, with the aid of follicular t helper cells in the spleen and lymph nodes, they continue to differentiate.
<h3>B-cell differentiation: </h3>
In reaction to the antigens, these cells develop in the bone marrow and create antibodies. Humoral reaction involves B lymphocytes. B cells create plasma cells and memory B cells as soon as they come into contact with the antigens.
In the spleen and lymph nodes, B-cells develop into plasma cells. An immunoglobulin receptor on each B-cell can bind to a single, distinct, unprocessed antigen. After being exposed to an antigen, B cells release interleukins to become active.
