Early in the segment, Lowe quipped that Adele was too young to have to lie about her age. Sessions for the album began when she was 25, though time has moved on. âI was 20 when 19 came out.
Serum (blood) In blood, the serum (/ËsÉªÉrÉm/ or /ËsÉªrÉm/) is the component that is neither a blood cell (serum does not contain white or red blood cells) nor a clotting factor; it is the blood plasma not including the fibrinogens.
The main difference between plasma and serum is the absence of fibrinogen, an important clotting factor, in the serum. Neither plasma or serum contain red or while blood cells or platelets, but they contain all the other substances, except for the fibrinogen, which is not present in the serum.
