What occurs if a t cell binds to an antigen and the t cell does not receive a co-stimulatory signal?
tresset_1 [31]
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.

Leona is making lemon pudding from "scratch." Her ingredients include fat-free milk, corn starch, lemon juice, egg yolks, salt,
lisabon 2012 [21]

Answer:

The acid in the lemon juice denatured the milk proteins.

Explanation:

The important biomolecule of the living organism is protein. Proteins are made of the repeating units of the alpha amino acids that are attached together through the peptide bond.

The proteins get denatured if they are subjected to the change in the temperature conditions or the additions of the chemicals. The addition of the lemon juice that acts as the acid coagulates the protein present in the milk and results in the clump formation.

Thus, the correct answer is option (a).
