One of the effects of dust is to cause

$A$: Dark reactions of photosynthesis are temperature-controlled processes.
$R$: Most of the reactions are enzymatic in nature.

If a chemical process is affected by more than one factor,then its rate will be determined by:

$A$ plants have a higher temperature optimum than the plants adapted to $B$ climate. Here $A$ and $B$ refer to:

In an experiment demonstrating the evolution of oxygen in $Hydrilla$,sodium bicarbonate is added to water in the experimental set-up. What would happen if all other conditions are favourable?
