Question and answer
Q: Anaerobic photoautotrophs were the first organisms to release oxygen into the early atmosphere. True False
A: False. Cyanobacteria are microbes that live primarily in seawater. They are believed to have been the first organisms on Earth to perform oxygenic photosynthesis. [ In this process, they produce organic carbon, the building blocks of life's molecules, and release oxygen gas (O2). The O2 enters into the seawater, and from there some of it escapes into the atmosphere. Please click "good" if this

User: How do you conduct the layering technique? You cut a piece of the plant's leaf, root, or stem off and bury it to produce adventitious roots and a new plant. You place the plant stem or bud into another plant with a good root system to grow a new plant. You bury a piece of the stem to produce adventitious roots and then cut the new plant away from the parent plant.

Weegy: You bury a piece of the stem to produce adventitious roots and then cut the new plant away from the parent plant.
