To make an argument about how environmental imbalance affects the ecosystem of the Chesapeake Bay, research on reliable sources on the topic is necessary.
<h3 /><h3>How is the Chesapeake Bay?</h3>
The bay corresponds to the largest ecosystem of estuaries in the USA, being a source of diverse types of habitat for wildlife, with more than 3,600 species of animals and plants.
An example of the environmental imbalance in the area is the commercial and recreational fishing of blue crab, whose population had a significant reduction in 2022.
Therefore, environmental factors and human exploration are responsible for generating such an imbalance, and the development of policies and actions to promote sustainability is essential.

Answer:
B cells produce antigen specific antibodies.
Explanation:
Adaptive Immunity:
- The adaptive or acquired immune system is an immune response system characterized by highly specific effector cells and immunoglobulins. Adaptive immune response identifies specific antigens and then elicits an immune response mediated by specific antibodies.
- Antibodies are exclusively produced by B-cells when they are activated by an antigen either directly through the B-cell receptor or through activation by T-helper cells.
- Once activated, B-cells proliferate into plasma cells and memory B-cells. Plasma cells can be thought of as antibody factories as they produce antigen specific antibodies.
- Memory B-cells remember the antigen and are able to elicit an immune response in case of further infections from the same pathogen.
