Answer:
“Stromatolites are pervasive in the fossil record and are some of our earliest examples of life on Earth,” he says. “The microbial mats that created them were predominantly made up of cyanobacteria, which used photosynthesis – like plants do – to turn sunlight into energy while producing so much oxygen over time they changed the early Earth’s atmosphere to make it habitable for complex life.

Explanation:
CUZ I AM SMART TRUST ME I DID THIS IN A TEST
<span>The experimental evidence that leads </span><span>scientists to believe that only quantized electronic energy states exist in atoms </span>was the Niels Bohr experiment on Hydrogen gas. The quantized model for electron orbits in atoms that effectively explained the spectroscopic behavior of the atoms. Each line in the spectrum corresponds to one exact frequency of light emitted by the atom.
