Explanation:
Prokaryotes: Organisms whose cells lack a nucleus and therefore have DNA floating loosely in the liquid center of the cell. Prokaryotes divide, and thus reproduce, by simple mitosis.
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.
Answer:
taking a closer look at the natural world
Explanation:
using prior knowledge is basic common sense. so no.
requiring evidence and thinking logically is following a rule. so no.
following strict rules when using human test subjects. right off the bat, "strict rules" is an immediate no.
taking a closer look at the natural world. that's creative because they look for the answer around them.
Protein is digested in the stomach when 3 main enzymes (pepsin, trypsin and chymotrypsin) break food protein into things called polypeptides, which are then broken down more into amino acids
