The correct answer is that "the T cell enters a state of anergy".
The activation of T cells requires two signals: (1) antigen specific signal presented by an antigen presenting cell (either a macrophage or a dendritic cell) that activates t cell receptors and (2) co-stimulatory signals that is not antigen specific but rather found in the plasma membrane of the antigen presenting cell (i.e. CD28). In the absence of a co-stimulatory signal, the t cell will enter a state of anergy or the inability to produce an immune response toward an offending antigen.
Maintaining the genetic diversity is long term solution which help to maintain polar bear population.
Explanation:
Polar bear from Norwegian way bears are genetically unique. These bears are only who survive in the world. they have lack genetic diversity so it is possible to they stay healthy and somehow survive in worst condition.
The climate and condition of Norwegian is way better so it is necessary to relocate the other polar bear. The other important thing is to ensure about their food. Polar bear mainly eat seal but due to the melting of ice they are unable to get proper food.
