Calculate the frequency of b cells specific for antigen a on day 36 if the antibody concentration on day 36 is about 8 × 103. (f
matrenka [14]
-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>

Atelectasis is caused by occupational exposure to coal dust.<br> a. true<br> b. false
Irina18 [472]
The statement is true. Atelectasis is the collapse or closure of a lung resulting in reduced or absent gas exchange. It may effect part or all of a lung. An airway blockage also can cause Atelectasis. A blockage may be due to a foreign object, a mucus plug, lung cancer, or a poorly placed breathing tube from a ventilator. When a blockage occurs, the air that's already in the air sacs is absorbed into the bloodstream.
