Capillaries: These tiny blood vessels have thin walls. Oxygen and nutrients from the blood can move through the walls and get into organs and tissues. The capillaries also take waste products away from your tissues. Capillaries are where oxygen and nutrients are exchanged for carbon dioxide and waste.

Nitya Shukla 4 years ago

The answer is wrong the correct ans is No l wouldn't agree to replace it by a copper wire because copper wire has less resistance so when too much current will pass through it , it will not melt and wouldn't break due to this there can be a big short circuit.

0Thank You

Divanshi Banerjee 4 years ago

Yes. I would agree, because 'Fuse' is will be more beneficial than copper wire. And fuse will also break the circuit when excessive current will pass through it. It can save us from big disaster's too.
