Answer:
MHCI
Explanation:
Major histocompatibility complex I (MHCI) is present on the nucleated cells of the body. Endogenous pathway represents the pathway of MHC class I molecules.
MHCI display peptide fragment of proteins to the cytotoxic T cells with the help of CD8 ( Cluster of differentiation). CD8 binds with the MHCI and expressed on the surface of cytotoxic T cells.
Thus, the correct answer is option (D).
By the term "condensed", this refers to the density of a state of matter. As a rule of thumb, solids are the most dense because their molecules are very close together. Next is liquids because they flow compared to solids. The least dense are gases. Therefore, a change from a more condensed state to a less condensed state is boiling (liquid to gas).
