If the metabolic rate of cockroaches at 15°c is 0.01 ml o2/hr and their metabolic rate at 25°c is 0.015 ml o2/hr. what is its metabolic rate at 20°c?

0.0035 mL of oxygen per hour is metabolic rate at 20°C at cockroach.

Explanation:

From the data we can see that metabolic rate of cockroach is in direct relation with temperature.

On graph, with metabolic rate on y-axis and temperature on x axis straight line will obtained , and the equation of the line can be determined by the help of point slope:

m = Slope of the line =

As per information given , :

x = temperature

y = metabolic rate

Now , put x = 20

y = 0.0035

0.0035 mL of oxygen per hour is metabolic rate at 20°C at cockroach.
