<span>Cells need a source of energy, they get this energy by breaking down food molecules to release, the stored chemical energy.This process is called 'cellular respiration'. The process is happens in all the cells in our body. Oxygen is used to oxidize food, main oxidized food is sugar(glucose).</span><span>Jan 14, 2009</span>

Isn't this Chem? 
a non metal and a metal 
a metal transfers electrons to the non metal
the non metal gains electrons and becomes an anion (a negatively charges ion)
and the metal loses electrons and becomes a cation (a positively charged ion)
        
             
        
        
        
Answer:
The components of abstracts that should be included are as follows: " introduction, Description, limitations, conclusion". Other than these components anything else should be excluded.
Explanation:
The various components of an scientific abstract that should be included are as follows:
Introduction: In this part of the abstract it should contain the brief idea about the research.
Description: In the second part it should contain the research and the objective of the research and also about the analytical methodologies that has been applied in the research.
Critical: This is part in which the limitation for the research are present. 
Language: The most important factor, the language used should be very formal type.
Conclusion: The things and ideas that had been learnt during the period of research. It should also contain the new findings and the trends that has came out during the research.
