-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>
Answer:
Reactions
Explanation:
Digestive enzymes help break down food into smaller, more absorbable components. They break down proteins into amino acids. Other enzymes orient chemical compounds so they can break up and form new products in the form of energy

Hope it helps plss mark as brainlist
Explanation:
This succession is influenced by environmental factors such as soil type, water regimes, vegetation history, climate, and invasive species. Humans affect all of these factors. ... More human presence in the landscape increases the risk of exotic invasive species spread
Endocrine glands: Thyroid, hypothalamus, and ovaries
