Una famiglia spende per il riscaldamento in due anni consecutivi rispettivamente 1425 euro e 2730 euro. Se la spe- sa per il combustibile è di 0,57 euro/m3 il primo anno e 0,65 euro/m3 il secondo anno, calcola il costo medio sostenuto
dalla famiglia nei due anni per un metro cubo di combustibile. Fornisci il risultato arrotondato ai centesimi.

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
