Answer:

- <u>Scientifically speaking, living things are alive because they have complex systems that allow them to be born, grow, reproduce and, when systems fail, die.</u>
Explanation:
The translation of the question is:
- why is a living being alive?
<h2>Solution</h2>
Answering from a scientific point of view, not a philoshophical one, a <em>living </em>organism is differentiated from a non-living entity in that the <em>living being</em> is born, grows, has the ability to reproduce and dies.
All that is possible because the living beings posses a complex network of systems that sustain their life.
Those systems include the homeosthasis, the metabolism, the answer to external stimulus, the ability of adaptation, the development (growing) and the reproduction.
To be considered a living being the organism must count wiht all those systems.
It is important that you know that viruses are not living organisms: they are chemical molecules which do not have metabolism and do not grow.
The answer should be "Dunes"
Answer:
at the oxygen end electron density lies
Explanation:
Carbonyl group is a functional group which is formed when oxygen combined with carbon through a double bond
So the carbonyl group is 
in this the oxygen has more electronegativity than carbon so oxygen attracts the electron density towards itself
So the electron density lies on the oxygen in a carbonyl group
