The subatomic particles of protons and neutrons are found in the nucleus of an atom. Protons are particles with a positive charge, while neutrons have no charge. Electrons, which have a negative charge, are particles that can found orbiting outside the nucleus of an atom.
        
             
        
        
        
Answer:
Figure 3
Explanation:
A mixture is a substance made up of two or more different kind of atoms arranged in such a way that they are not chemically linked or joined. This accounts for the reason a mixture can be separated easily. In the figures attached as an image in this question:
- Figure 1 represents an element because it is made up of only hydrogen atoms chemically bonded together to form a molecule. 
- Figure 2 represents a compound because it contains hydrogen and carbon atoms chemically joined together. 
- Figure 3 represents a MIXTURE because it contains the oxygen and carbon atoms, which are not chemically joined to one another. As seen in the image, the oxygen atoms are not joined to the carbon atoms. 
- Figure 4 represents a compound because it contains oxygen and hydrogen atoms chemically bonded together. 
 
        
             
        
        
        
Fragmentation is the breaking of the body into parts and then the organism develops all the parts of the body. The fragmentation is the type of reproduction in lower organisms. The fragments which are produced can develop into new organisms.
 
        
                    
             
        
        
        
A light microscope, I don't think it would be an electron microscope because we're talking about PRESERVED plant cells.
        
                    
             
        
        
        
it's b. anaphase and spindle fibres pulls chromosomes towards the centrioles in this phase.
