Nucleic acid is the macromolecule that carries code for building our body.
The digestive system, it breaks down the material into nutrients and the circulatory system then carries it out to the cells throughout the body. hope this helps!!!

λ= wavelength
f= frequency
v= λf
v= 25 x f
You'll need the wave frequency to complete this equation
