Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification.
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.

I want to Say A - I searched google and it said that Archaea has something called membrane lipid bonding, ( which is oils and fat ) I didn't see anything about nucleus, size, or cell wall.
Hope this helped!
Abiotic factors in common ecosystems:
1: Bats are interesting creatures, and use echolocation to make food
2: The cave walls help spread the voices of the bats
3: They have to use echolocation to breathe
Biotic factors:
1: Some good roles for bats are predators
2: They effect the system of computers when they bite computer chips
3: They complex human system life<span />
Los seres invertebrados y los vertebrados tienen más elementos en común de lo que se pensaba. Un estudio, con participación del Consejo Superior de Investigaciones Científicas (CSIC), prueba que existe gran similitud entre los sistemas excretores de ambos grupos de animales. Según la investigación, las células encargadas de filtrar la sangre en la formación de orina, alojadas en los riñones de vertebrados, son similares a las que realizan una función análoga en invertebrados.
