The "Cranes" is a short story book written by Hwang Sunwon. The story is set in Korea during the Korean War and focuses on two childhood friends, Songsam and Tokchae, who are on opposite sides during the war. Songsam has two flashbacks of his childhood memories with his friend Tokchae, where he remembers how they used to climb the trees and catch cranes. These flashbacks act as a reminder of the times he had spent with his friend and the importance of this friendship. As a result, these memories motivate him to let Tokchae free.
-The number of B cells producing the antibody is proportional to the concentration of that antibody.
-On day 16, one out of 100000 B cells are specific for antigen A
\frac{1}{100000} = 1 x 10⁻⁵ B cells
- on day 16, Antibody concentration is 2 × 10¹= 20 Antibodies
- on day 36, antibody concentration 8 × 10³.= 8000
20 antibodies ------------ 1 x 10⁻⁵ B cells
8000 antibodies--------------x
x= (8000 x 1 x 10⁻⁵)/ 20
x= 4x10⁻³ or 1 in 250 are <span>B cells specific for antigen A</span>
