This is a simple calculation involving drug doses.
The solution is as follows:
(0.125 mg/tablet)(n) = 1.25 mg
n = (1.25 mg)/(0.125 mg/tablet)
n = 10 tablets
So a person needs to take ten 0.125 mg tablets of vitamin D to have that 1.25 mg dose.
        
             
        
        
        
Microtubules are composed of two different types of tubulin. Namely, these simpler units are called alpha-tubulin and beta-tubulin. These subunits are essentially tightly bound together to form heterodimers. In the microtubule structure, they are arranged in an organized manner in such a way that they in parallel direction with protofilaments.
