Question

4. The amount of surface area in relation to volume would influence how rapidly one chills in an ice bath? Below are the surface to volume ratios of five people to compare. Who would survive the longest if dropped into icy cold water? A. 9:10 B. 0.64 C. 1:2 D. 2 E. 0.15 5. Under normal physiological conditions, the Q10 rule has little influence on humans. Why? A. Humans are endotherms. B. Humans "keep the engine running" at high temperatures. C. Humans maintain a relatively constant internal body temperature despite fluctuations in the external environment. D. All of the above are similar and correct reasons. E. None of the above is an explanation.

Explanation / Answer

4. The rate of cooling is inversely proportional to radius (size) of the animals. So, if the radius is less i.e. small animals cools faster compared to larger animals. So, the option E cools slowly and survives long time because it has high radius(based on given surface area to volume ratio) when compared to all others.
