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 structure is calcium ions.
Diversity is produced by mutation, it is what causes life to have advantages or disadvantages, and thus allow survival of the fittest to choose which mutation is the best suited for it's environment.
Proteins is used to build and repair cells.
Protein can be found in every living cell and it is very
important building block in the body. Protein supply amino acids which were
being used to create and repair cells, enzymes, red blood cells, antibodies and
tissues. In the body, protein functions by maintaining fluid balance and
transportation substances. Protein can be gotten from meat, dairy products, soyabeans,
nuts, beans and certain grains. However,
protein from meat and other animal products are known as complete protein.
It reduces
Explanation:
The density of the heated mantle rock reduces because its volume has increased.
- Frictional heat, heat from radioactive decay and heat that accretted originally when the earth was forming are responsible for heating the mantle.
- When a substance is heated, it expands and its volume increases.
- Density is a function of mass and volume.
- The higher the volume, the lower the density.
- The higher the mass, the higher the density.
- When the mantle is heated, its volume increases to a new one and its density reduces.
