Two atoms of oxygen element are represented as "20". The two oxygen atoms are unreactive state and are unstable readily reacts and form molecules.
O₂ reprersents one molecule oxygen. When the two oxygen atoms reacts with each other forms one molecule of Oxygen. After the formation of Oxygen molecule, it (oxygen) has got stability.
The coast is warmer and better environment
Answer:
Competitive exclusion occurs when " organisms attempt to fill the same niche"
Explanation:
mostly due to the fact that they are competing over the same food source, which is always limited in some way.
During photosynthesis, plants absorb carbon dioxide and sunlight to create fuel—glucose and other sugars—for building plant structures. This process forms the foundation of the fast (biological) carbon cycle. ... In all four processes, the carbon dioxide released in the reaction usually ends up in the atmosphere.
Cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called prokaryotes.
<h3>What are prokaryotic cells?</h3>
Prokaryotes are organisms whose cell (or cells) are characterized by the absence of a nucleus or any other membrane-bound organelles.
Prokaryotic cells are opposed to their eukaryotic counterparts that possess a membrane-bound nucleus that houses their genetic material (DNA).
Examples of prokaryotes are as follows:
Therefore, cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called prokaryotes.
