can somebody give me an example of invention related with life...example: mosquito killer...?

Answer 1

Well, mosquito killer is actually related to death, not life... :)

Anyhow, I'm not sure exactly what you mean but what about:

DNA fingerprinting - as a means of identifying criminals?
Silk, taken from silkworms to make garments, or cotton from cotton plants.


There are lots of examples, but a huge number of things are indirectly related to life.

For example, a polythene (plastic) bag.

Polythene is made from polyethylene generated by the petrochemical industry. The oil the industry uses is essentially superheated organic debris from dead zooplankton and algae that settled after death...

So all the gas you run your car on is really biofuel from dead microscopic plants and animals.

Coal originates from dead plants which have been compacted and hardened over time.

There are thousands of other examples.

Answer 2

I'm not sure I understand your question. All inventions are related with life: necessity is the mother of invention. If there's not a need for something, nobody thinks to invent it. Everything that's been invented was invented to solve a problem. Does this answer your question? Maybe you need to add more details for us...
