The Figure Below Illustrates Distance and Diffusion Time;note That the Time

Multiple Choice

The figure below illustrates distance and diffusion time;note that the time required is NOT directly proportional to the distance.Why,for the insect and mouse,might an increase in distance of 20-fold require an increase in time of 60-fold?

A) Oxygen reacts chemically as it diffuses,becoming less diffusible as it travels greater distances.
B) Larger animals are warmer than small animals;the rate of diffusion is dependent,in part,on the temperature.
C) As oxygen disperses into a large area,its concentration declines;the rate of diffusion is dependent,in part,on the difference in concentration between two locations.
D) Organisms are able to manipulate the rate of diffusion so that the delivery of oxygen matches their metabolic activity levels.
