Answer:
The interaction of cell surface receptor extracellular domains with secreted ligands is essential to most types of cell signaling and cell-cell communication. This initial step and the subsequent activation of membrane-proximal and -distal intracellular signaling cascades lead to specific, although often redundant, cellular responses that control cell proliferation, differentiation, maturation, and survival. Cell surface receptors usually bind their ligands through highly specific molecular interactions to provide the tight regulation necessary for control of physiological responses. However, researchers increasingly appreciate that many receptor systems exhibit, to a greater or lesser extent, cross-reactivity with a spectrum of different ligands
Explanation:
C is the answer, (metaphase) because during metaphase the sister chromatids align along the equator of the cell by attaching their centromeres to the spindle fibers. (for plato)
