Problem 3

Question

At the end of a basketball game, the opposing teams line up and file past each other and shake hands. This efficient exposure of the teams to each other is analogous to: a. countercurrent exchange of gases in fish gills and bird lungs. b. diffusion of \(\mathrm{O}_{2}\) from blood to cells in shark tissues. c. diffusion of \(\mathrm{CO}_{2}\) from cells to blood in crabs. d. utilization of \(\mathrm{O}_{2}\) in cells in insects. e. excretion of \(\mathrm{CO}_{2}\) from mammalian cells.

Step-by-Step Solution

Verified
Answer
The correct answer is a. Countercurrent exchange of gases in fish gills and bird lungs.
1Step 1: Understand the analogy
In this step, we need to understand the concept of the basketball scenario. Here, the teams are facing each other and then they are passing by each other line by line and finally getting to the other side. This is a systematic and efficient exposure.
2Step 2: Analyze the given options
Here, we have to identify which biological phenomenon resembles the basketball scenario. Analyze the options one by one:\n\na. Countercurrent exchange in fish gills and bird lungs denotes a mechanism where two streams flow in opposite directions thus allowing maximum exposure between the two. This looks similar to the basketball scenario.\n\nb. Diffusion of \(\mathrm{O}_{2}\) in shark tissues is not matching as it's a random process not the systematic exchange.\n\nc. Diffusion of \(\mathrm{CO}_{2}\) in crabs is same as option B, it's not a systematic process.\n\nd. Utilization of \(\mathrm{O}_{2}\) in insects. Use of oxygen in the insects happens inside their bodies and doesn't replicate the basketball scenario.\n\ne. Excretion of \(\mathrm{CO}_{2}\) from mammalian cells. It's a one-way process where CO2 is removed from the cells, again this is not a proper analogy.
3Step 3: Find the Correct Option
Considering the basketball scenario's systematic and efficient exchange and comparing it to the biological phenomena given in the options, the countercurrent exchange of gases in fish gills and bird lungs appears to be the closest match as it also demonstrates a systematic exchange process.
