Theories are often the best explanations of natural phenomena we currently have. Yet, what one has to realize is that science is ever changing. That is why (B) is the correct answer, as new examinations, experiments, and discoveries could change some of these well-accepted theories. There is no way to "harm science" with viable observations and discoveries so (A) is incorrect. Answer (D) is also wrong since there is no assurance that a theory will never change in the future as they are merely accepted hypotheses. Answer (C) is not the best answer since theories are usually well supported and wouldn't be veritable if every examination proved flaws.
Hope this helped! :)

Sensory neurons
Process
Light falls onto retina. The retina generates an impulse that is carried to the brain by the sensory neurons. An impulse is not carried by blood vessels, so that crosses out A. A muscle cant carry impulses either. Spinal cord isnt the answer because it doesnt have to go through the spine because the eye and brain is so close together
Answer:
Easy
Explanation:
Photosynthesis turns carbon into oxygen, and respiration puts carbon back in the air
