Think about the following examples of homeostatic regulation: in response to an increase in plasma k+ concentrations, the hormone aldosterone brings k+ levels back to normal. in response to a decrease in plasma ca2+ concentrations, parathyroid hormone brings ca2+ levels back to normal. which of the statements below is true?

Fine out you self hx

The answer is not c

Convection is da answer my dood

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -
