Answer:
Coronavirus in its own doesn't have an advantage. 
I believe that it helps us to prevent other epidemic diseases such as cholera and other diseases that are caused by lack of sanitization. 
Since washing hands frequently is the way of preventing coronavirus. 
And wearing mask also helps us to prevent other respiratory diseases being transmitted.

Answer:An inherited, natural selection.
Explanation: Adaptation is the process through which living organisms develop mechanisms this mechanisms may be Inherited to enable them survive competition and other prevailing circumstances. Which can also be environmental, climatic factors etc.
Adaptation helps to ensure the principle of NATURAL SELECTION,where organisms which have been able to develop similar mechanisms or have natural mechanisms that has enabled them to survive the prevailing circumstances in the habitat. 
 
        
             
        
        
        
Answer:
Binary fission is different from mitosis and meiosis because it occur in prokaryotic cells. And prokaryotic cells does not have nucleus like the eukaryotic cells and there is not mitotic spindle formation during binary fission compared to mitosis and meiosis.
Explanation:
Binary fission is a process of cell division where a single cells divide into two or more parts and the parts regenerate into another organisms which resembles the parent organisms. This occur only in prokaryotic cells and is very different from mitosis and meiosis that occur in eukaryotic cells because prokaryotic cells lack nucleus and no spindle formation in the nucleus.
Mitosis occur in eukaryotic cells because they have nucleus and membrane bound organelles and is the process where a parent cell divide to produce two daughter cells that are genetically identical to the parent cell and each cell having the same number of chromosomes of the parent cell.
Meiosis is a type of cell division that occur in eukaryotic cells and it occur in sex cells where a single cell divide into four daughter cells with each having half number of parent cell chromosomes.
