Question

#1: chapters 1-2-3 and 4
which of the following is true regarding comparative physiology?
check all that apply
it is necessary because human experimentation is limited.
it led to the development of imaging technology, such as ultrasound and mri.
it is the basis for the development of new medications and medical procedures.
it has provided little to no help in pharmaceutical research.
it is the reason why surgeons may practice on animals before they work on humans.

Explanation:

Comparative physiology studies physiological processes across different species. Human experimentation has ethical and practical limitations, so comparative physiology on other species is necessary. It helps in understanding biological processes which is fundamental for new medications and medical procedures development. Surgeons practice on animals as part of learning based on comparative - physiological knowledge. Imaging technology development is not directly due to comparative physiology, and it has significant contributions to pharmaceutical research.

Answer:

It is necessary because human experimentation is limited.
It is the basis for the development of new medications and medical procedures.
It is the reason why surgeons may practice on animals before they work on humans.
