Question
22. Assume you are a red blood cell. It is your responsibility to load up on oxygen as fast as possible in the lungs and then deliver it to cells elsewhere in your body. Which of the following would increase your chances for the rapid diffusion of oxygen? A. Increase the number of Mitochondria. B. Become large and spherical. C. Become flat or elongate. D. Increase volume while holding surface area constant. E. All of the above. 23. Which is the broadest explanation of why evolution occurs? A. Homeostasis is the goal which evolution always pursues. B. Mutations must occur in order for gene frequencies to change. C. Some individuals have differential reproductive success and thus leave more offspring and their genes to reproduce in the next generation. D. Entropy causes organisms to become more and more complex E. Dynamic Homeostasis causes all organisms and their traits to be con changing day-by-day. stantlExplanation / Answer
22. For rapid oxygen diffusion by RBC it is mandatory to increase the surface area not volume. So option B and D got eliminated as they increase the distance of the distance for the oxygen to diffuse to reach the center of the cell.
Option A is incorrect as there are no mitochondria in the RBC to maximize the cell surface to carry more oxygen.
In this way only the option B that flat or elongation of RBC can help in increasing rate of the diffusion of the oxygen. So option B is correct.
23. Option E is the most broad option because it says that the dynamic homeostasis cause all the organisms and their traits to be constantly changing day by day. It explains that dynamic homeostasis lead to the various processes to occur for the survival of organism. There will be mutation, migration as well as variation due to entropy change in the continuous homeostasis process that will consequently lead to the evolution of the organism.
