Do bulbs in series have the same brightness? Placing cells in series increases the voltage in the circuit by 1.5 V for each cell. Increasing the number of bulbs in a series circuit decreases the brightness of the bulbs. In a series circuit, the voltage is equally distributed among all of the bulbs. Bulbs in […]

Does the stomach produce mucus?
Does the stomach produce mucus? The stomach has a two-layered mucus system, composed of an inner, attached mucus and an outer, unattached, loose mucus layer, both built by the MUC5AC mucin produced by the superficial epithelium.
