question 30\n5 points save answer\na research lab utilizes rats to observe the effect of creatine on muscle growth and cognitive function over a chronic period of time. as technology has improved and advanced, there is now a computer model that can replicate the lab protocol on the rats. a lab technician brings this to the attention of the principle investigator (pi) as this would lead to no longer needing rats as subjects. however, the pi waves off the technician and responds that they do not have time to learn this new system and retrain the laboratory technicians.\n1. this example falls under what principle of animal - subject ethics? (2 points)\n2. did the pi act ethically? why or why not? (3 points)\nfor the toolbar, press alt+f10 (pc) or alt+fn+f10 (mac).

Answer

Brief Explanations:

  1. The principle of replacement in animal - subject ethics involves using non - animal alternatives when available. Here, the computer model is a non - animal alternative, so this example falls under the replacement principle.
  2. The PI did not act ethically. The replacement principle aims to reduce animal suffering. By not adopting the computer model due to time constraints for training, the PI is choosing to continue using animal subjects when a non - animal alternative exists.

Answer:

  1. Replacement
  2. No. Because there is a non - animal alternative (computer model) available, and the PI is choosing to continue using animal subjects due to time constraints for training technicians instead of adopting the alternative to reduce animal suffering.
