Question: Surface areas are important in biology because they constrain the rates of transfer of light, heat, water, gases, food, forces, etc. Discuss and contrast the location, orientation and size of at least two surface areas for two animals of contrasting lifestyles (i.e. at least two surface areas per animal). Give both the common and scientific names of the organisms. How do the placement and size of the transport surfaces match the lifestyle of each species? Use quantitative examples and arguments if you can. Unusual animals or lifestyles are welcome. Consider the phylogenetic history in your comparisons. For instance you might predict animals from the same family or genus with different diets might have differences in their digestive systems

After a few minutes, the light should begin to look brighter. Even as this is the case, add a card and see if you can still see light. Repeat this process of gradually adding cards over a 15-minute period. Were you able to detect an increasingly dim ..
