High concentration and passive transport
Among the ones listed above, the statement that best describes the way that the periodic table is arranged is "<span>The nonmetals are grouped together, which the exception of hydrogen.</span>" It can be seen that all of the nonmetals are placed on the far right of the periodic table except for hydrogen.

Stem cells arise from the inner mass of the cell
Signalling factors trigger differentiation in stem cells
Genes that lead to the production of undifferentiated blood cells are activated
Signalling factors cause undifferentiated blood cells to produce red blood cells
Explanation:
Red blood cells are formed in the bone marrow. The precursor to the RBC is stem cell which is undifferentiated and pluripotent. The stem cell gets differentiated to form immature RBCs. Immature RBC then gets divided and becomes mature. Stem cell giving rise to RBC is called Haemoctytoblast. The process of erythropoiesis takes 2 days to form new red blood cells
