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.

Explanation:
Correct answer: B). Cells spend the most time in interphase, where they grow and their DNA replicates.
The cell spends its most of the time in the interphase, during this phase of growth, cell continues to grow and carry out its metabolic activities which are necessary for regular growth and maintenance.
During this phase of the cell cycle, a lot of protein is synthesized in order to double its size. The important changes that occur in this phase include DNA duplication and division of chloroplast and mitochondria.
Hence, the correct answer would be option B.
Answer:

it would have no food.
Explanation:
Photosynthesis also uses carbon dioxide faster than respiration produces it. Oxygen surplus is released into the air and unused glucose stored in the plant for later use. This is why plants are so important to human and other animals' survival. Without photosynthesis, we wouldn't have oxygen or food to stay alive.
Plant cells respire, just as animal cells do. If they stop respiring, they will die. Remember that respiration is not the same as breathing, so take care - plants do not breathe.
