They are both biotic factors because they affect living organisms. The abiotic factor a lion and deer needs is water because they need to stay hydrated but water is not living . Deers eat plants, plants are known as biotic factors too. And lions eat their prey which are living animals and once they are preyed upon they are still considered biotic because they were once living before getting consumed by the lion.
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.

Answer:
The agent causing the pneumonia, where bluish-green pus was found, is most likely Pseudomonas aeruginosa.
Explanation:
Pseudomona aeuriginosa is a gram-negative bacteria that is one of the main causes of hospital-acquired infections, including pneumonias in mechanically ventilated patients.
One of the characteristics of P. aeuriginosa is the formation of a bluish-green pus, since it has the capacity to form cyanide-based blue pigment upon contact with the organic tissues it infects. This is the reason why previously P. aeruginosa was called a pyocyanic bacillus.
<em> The other options are not correct because the only bacterium that produces blue-green pus is P. aeruginosa.</em>
