Imagine that you just completed a titration of a known volume and
concentration of an acid with a known volume of a base but an unknown
concentration.
You added 25 mL of 0.25 M HCl acid in order to neutralize 75 mL of NaOH.
1. What was the calculated concentration of the base?
2. Why is this called a neutralization reaction?
3. What are the products of the reaction?

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
