Cyanobacteria start producing pure oxygen around 200 million years ago.
<u>Explanation:</u>
Many scientists believed that Earth did not have any oxygen. Cyanobacteria or the blue green algae are the microbes which produced oxygen for the first time with the help of photosynthesis. This was around 4.5 billion years ago: after Hadean eon.
They were very simple, but they produced oxygen in the early earth’s atmosphere. So, they brought evolution on earth. This “blue-green algae” exists in salt water, rocks and soils and play a major role in maintaining the ecosystem.
Answer:
A. the root is continuing to grow so the cells are going through mitosis
To clarify, you should read the directions that come with the lab activity to be sure of what to do in the lab.
At the point when the wind transports silt by saltation, little particles are brought about to "bob" or "bounce" by the wind, moving them toward the path the wind is blowing. Essentially, the particles are skiped along the surface once or a few times until they lose energy and additionally lift from the twist, and soon thereafter they rejoin the silt on the ground. It is a type of transport that for the most part prepares little particles, however the size increments with expanded wind speed.
