A genetic change that occurs in a body cell of a mouse will not contribute to the continued genetic diversity of the species because.
Answer:
The genetic material in the germline cells is passed onto offspring, not somatic cells.
Explanation:
A body cell is another terms for somatic cell. Germline cells refer to cells involved in reproduction, like the egg and sperm. During reproduction, only these cells combine to start creating the new life. Therefore, the genetic changes that occur in body cells have no effect on the offspring because the change is not also found in the germline cells. Should there be genetic changes in the germline cells, then these alterations would be present in the offspring.

bacterial lipopolysaccharide causes which type of reaction?
:
Lipopolysaccharides (LPS) are one of the main causes of systemic, low-grade inflammation!
!
Bacterial lipopolysaccharide (LPS) can cause an inflammatory reaction.
LPS is a component found in the outer membrane of Gram-negative bacteria. When released or exposed to the immune system, LPS can trigger a strong immune response and induce inflammation.
LPS activates the innate immune system through the recognition of specific structures within LPS by immune cells, particularly toll-like receptor 4 (TLR4).
Activation of TLR4 initiates a signaling cascade that leads to the production and release of various pro-inflammatory cytokines, such as tumor necrosis factor-alpha (TNF-alpha), interleukin-1 (IL-1), and interleukin-6 (IL-6). These cytokines contribute to the initiation and amplification of the inflammatory response.
The inflammatory reaction caused by LPS can result in symptoms such as fever, increased vascular permeability, activation of immune cells, and the release of other inflammatory mediators. In severe cases, excessive or uncontrolled immune response to LPS can lead to systemic inflammatory response syndrome (SIRS) or sepsis, a life-threatening condition.
In summary, bacterial lipopolysaccharide (LPS) causes an inflammatory reaction by activating the immune system and triggering the release of pro-inflammatory cytokines, leading to inflammation and associated symptoms.
