Tissue: a cellular organizational level between cells and a complete organ + an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function
Answer:
Ca(OH)2 (aq)
Explanation:
The balanced neutralization reaction i.e. a reaction between an acid and a base, in this question is given as follows:
H2SO4(aq) + Ca(OH)2(aq) → CaSO4(aq) + 2H2O(l)
According to Arrhenius in his definition of acid and base, a base is a substance that dissociates into hydroxide ions (OH-) when in an aqueous solution. In other words, a base increases the concentration of hydroxide ions when dissolved.
In this reaction, Ca(OH)2 releases the OH- (hydroxide ion) that combines with the hydrogen ion (H+) released by the acid, H2SO4, to form water (H2O). Hence, Ca(OH)2 (aq) is the BASE.

Answer:
Airborne transmission may occur if patient respiratory activity or medical procedures generate respiratory aerosols. These aerosols contain particles that may travel much longer distances and remain airborne longer, but their infective potential is uncertain. Contact, droplet and airborne transmission are each relevant during airway manoeuvres in infected patients, particularly during tracheal intubation.
