An enzyme-catalyzed reaction was run at five different temperatures (trials 1-5). the results are shown in the data table above. based on the data, which of the following is correct?

this enzyme functions optimally at 30°c.
this enzyme functions optimally at 70°c.
this enzyme is denatured at 30°c.
this enzyme is denatured at 70°c.

(i think its the first one)

How does upwelling affect coastal fisheries? upwelling damages nutrient supplies at coastal fisheries as the warm, nutrient-rich surface water is replaced by nutrient-poor, cold water. upwelling damages nutrient supplies at coastal fisheries as the cold, nutrient-rich surface water is replaced by nutrient-poor, warm water. upwelling improves the nutrient supply at coastal fisheries as the warm, nutrient-rich surface water replaces the nutrient-poor, cold water. upwelling improves the nutrient supply at coastal fisheries as cold, nutrient-rich water replaces the warm, nutrient-poor surface water.
