Answer:
By identifying and “crossing” grasses that exhibited the desired traits, farmers were able to breed these two distinct species. The difference between GMOs and their selectively bred predecessors is that with selective breeding, all the traits of the desirable animal or plant are passed on to the new offspring

A proton has a positive (+1) charge, while a neutron is electrically neutral (carries no charge).
3) the pistil
The bottom of the pistil contains the ovary and the narrowed region in between is called the style. The male contribution or pollen is produced in the anther, and seeds develop in the ovary.
Given what we know, we can confirm that the significant increase in oxygen in the Earth's atmosphere 2 to 2.5 billion years ago is due to cyanobacteria.
<h3>What are cyanobacteria?</h3>
These are tiny bacterial organisms. They were amongst the first organisms to use photosynthesis to sustain life. The sudden boom of cyanobacteria accounts for the rapid increase in oxygen given that they will use carbon dioxide to produce sugar through photosynthesis, expelling oxygen in the process.
Therefore, we can confirm that the significant increase in oxygen in the Earth's atmosphere 2 to 2.5 billion years ago is due to cyanobacteria.
