1 answer:
xeze [42]3 years ago

Answer:

"The earliest evidence for life on Earth comes from fossilized mats of cyanobacteria called stromatolites in Greenland that are about 3.7 billion years old. Ancient as their origins are, these bacteria (which are still around today) are already biologically complex—they have cell walls protecting their protein-producing DNA, so scientists think life must have begun much earlier."

What type of change is boiling water? why
Rasek [7]
Boiling water is a physical change. This is because the water that is being changed into a gas, and can be changed back. Bohr proposed a theory that helped make the blueprint for the atomic model. Gold is a soft but heavy metal, and reflects light with a green/blue hue. Gold is a shiny yellow to canary yellow in colour, and is often confused with pyrite, or 'fool's gold'. The particles in a solid vibrate in place, and are very close together. When one atom of carbon and two of oxygen meet, the make a bond that in turn creates CO2 or carbon dioxide. I hope I helped. :)
