When a stem cell divides, it first becomes an immature red blood cell, white blood cell, or platelet-producing cell. The immature cell then divides, matures further, and ultimately becomes a mature red blood cell, white blood cell, or platelet.

Evolution is the process of change over time and Darwin explains in his theory the changes in humans over time and <span>shows how the living world is constantly changing.</span> This is the reason why cientists refer to charles darwin’s ideas about evolution as the theory of evolution.
-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>
First i would like to discuss the design with the head of the construction crew that are capable of understanding the engineering part, then ask him if the design is feasible, if its realistic, if it is safe to be house and if it is safe to work on by the workers. and it would be his task to deliver it the others
