Explanation:
Detailed explanation-1: -A second round of experiments confirmed the results. “It became clear that there was something happening in there that we couldn’t explain with the information that we had, ‘’ said Maresca. Additional experiments revealed that the bacteria grew faster in blue light and UV light, but not in red or green light.
Detailed explanation-2: -In dark rooms, about 12 percent of bacteria, on average, were able to reproduce, the researchers at the University of Oregon found. But in sunlight, only 6.8 percent thrived. That was down to 6.1 percent for bacteria exposed to UV light.
