Allergic responses to inhaled antigens occur when an individual is first sensitized to the antigen (i.e., the allergen), inducing an immune response and then has a subsequent exposure to the same antigen. The sensitization phase is characterized by <u>Induction of a CD4 T cell type II immune response</u>.
The process by which your body becomes sensitive to a particular substance is called sensitization. When your immune system becomes sensitized to an allergen, you can develop certain symptoms.
Antigens that can induce an allergic response are called allergens, and they are often derived from non-infectious or non-microbial sources.

The birth rate was greater than the death rate and the immigration rate was greater than the emigration rate. Options B and D are correct.
<h3>Population growth</h3>
From the illustrated image, the world experienced an upward growth in population between 1950 and 2010.
In order for population growth to occur:
- the birth rate must exceed the death rate
- immigration must exceed emigration
Either or both of the above conditions will lead to a growth in the population.
Thus, options B and D are correct.
