Hey there! Let's solve the problem:
CD4 T cells activate CD8 T cells through an underhanded cycle including an antigen presenting cell (APC), customarily a standard dendritic cell (DC). An APC presents a peptide to a true CD4 T cell through a Class II MHC molecule.
<span>Archaeas and Bacterias are both Prokaryotes. Both used to be classified in Monera kingdom, but later genetists found that they have actually very different genes, despite they both have a similar metabolism. So they think they have a totally different evolutionary origin and they decided to classify them in 2 different domains. The other domain, Eukarya, includes every other organism (all the ones who are not Prokaryots), which are: plants, animals, fungi and protists.</span>
Answer:
Uvula.
Explanation:
Respiration may be defined as the process of exchange of gases between the body tissue, lungs and the environment. Oxygen is inhaled and carbon dioxide is exhaled out during the process of respiration.
The choanae, external nares, epiglottis and mouth plays an important role in respiration. Uvula is mainly involved in the production of the salivary gland. The uvula moistens the area and also involved in the speech process. Hence, uvula do not play important role in respiration.
Thus, the correct answer is option (b).
