can someone tell how to do this?

Explanation:

Temperature

As you increase the temperature, the rate of reaction increases. This is because particles move more quickly at a higher temperature, increasing their chances of colliding and engaging in a chemical reaction!  

The reason it isn't a straight diagonal line is because a certain amount of energy is required before the reaction can begin (i.e. a minimum temperature). The peak represents the optimum condition for an enzyme to perform its functions in. However, if the reaction temperature is too high, the enzyme is denatured and destroyed, so the reaction rate drops.

pH

Enzymes tend to have an "optimum" pH at which they work best. At the optimum pH, the enzymes can successfully perform their functions, outside this range, their efficiency can drop, and at extremes could become denatured.

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.
