The specific proteins produced by cell B in response to the foreign substance are antibodies.
<h3>What are antibodies?</h3>
Antibodies are specific proteins produced by the immune cells of the body in response to a foreign substance called antigen which produces the immune response.
Antibodies are released by immune cells such as B cells.
The antibodies bind to antigen and tag them for destruction by phagocytes.
Therefore, cell B will produce antibodies.

Can you add more context to your question i’m confused
The molar mass of the unknown compound is <u>223.2 g/mol.</u>
<u />
Solution:
Molarity = 
Molecular weight =<u> 223.2 g/mol</u>
<u />
The main difference between the two is that molar mass refers to the mass of one mole of a particular substance. Molecular weight is the mass of a molecule of a particular substance. Although the definitions and units of molar mass and molecular weight are different, the values are the same.
The formula mass of a molecule is the sum of the atomic weights of the atoms in that molecular formula. The molecular weight of a molecule is the average mass calculated by adding the atomic weights of the atoms in the molecular formula. Molecular weight is the mass of a single molecule, specifically the mass of material required to make a single mole.

Answer:
0.1 m C6H12O6 < 0.1 m NaCl < 0.1 m Cu(NO3)2 < 0.1 m Fe(NO3)3
Explanation:
Step 1: Data given
ΔTb = Kb*m*i
⇒with Kb = 0.512°C/m
⇒with m = molality
⇒with i = Van't hoff factor = the number of particles into which the solute dissociates
a. 0.1 m NaCl
⇒ molality = 0.1 molal
⇒ i(NaCl) = 2 ( dissociates in Na+ and Cl-)
0.1 * 2 = 0.2
b. 0.1 m Cu(NO3)2
⇒ molality = 0.1 molal
⇒ i(Cu(NO3)2) = 3 ( dissociates in Cu^2+ and 2NO3-)
0.1 * 3 = 0.3
c. 0.1 m C6H12O6
⇒ molality = 0.1 molal
⇒ i(C6H12O6) = 1 ( doesn't dissociate in water)
0.1 * 1 = 0.1
d. 0.1 m Fe(NO3)3
⇒ molality = 0.1 molal
⇒ i(Fe(NO3)3) = 4 ( dissociates in Fe^3+ and 3NO3-)
0.1 * 4 = 0.4
0.1 m C6H12O6 < 0.1 m NaCl < 0.1 m Cu(NO3)2 < 0.1 m Fe(NO3)3
