ADULTHOOD
INFANCY
BIRTH
1. A child learns to walk, talk
and begin to be more self-sufficient at
this stage
2. A child is completely
dependent on the care of his parents in this
stage.
3. It is the stage that the boys

5. Girls at this stage begin to
menstruate ad are now capable of
giving birth.​

Adulthood = 3 and 5

Infancy = 1 and 4

Birth = 2

Explanation:

Assuming that the Kd values of A are 9.1x10 (-5), B 3.2x10 (-11), and C 2.7x10 (-6) for IgG1 immunoglobulin, antigen A is considered to have the least affinity for the antibody. , then followed by antigen C and lastly B.

Regarding the Kd of the antigens with respect to IgG2, they are: A 4.0x10 (-10) B 7.4x10 (-10) and C 1.8x10 (-11), considering that the antigen that has the least affinity to said antibody is the B, then followed by A and finally C

Explanation:

It is important to know that the dissociation constant is inversely proportional to Kd, that is, to the association constant, this means that it is indirectly proportional to affinity as well.

This is why the dissociation constant = 1 / Kd.
