Detailed explanation-1: -Which of the following statements best helps explain how cell surface proteins, such as MHC proteins and T cell receptors, mediate cell communication over short distances? The proteins receive electrical signals from nerve cells.
Detailed explanation-2: -Which of the following statements best explains Delta’s role in regulating cell communication through the Notch signaling pathway? Delta restricts cell communication to short distances within a developing embryo.
Detailed explanation-3: -Cell-to-Cell Communication Some cells in the body can capture these antigens and display them on their surface in receptors. The receptors and antigens then can bind to other immune cells, activating them and showing them exactly what to look for. These cells are called antigen-presenting cells.
