Theories basic to all of the life sciences include the cell theory because all living things are made up of cells.
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.

Answer: The adaptations like paddy feet and fur on the outer body is an adaptation for very cold place but not for the rain forest.
Explanation: If the outer body of the organism is made of fur then it will protect the inside body from cold and will provide warmth.
But if the body will have adaptation like fur in the rain forest then it will make the organism wet so there will be no use of fur on the outer surface of the organism.
The adaptation like camouflage will help the organism in the rainforest so that it can hide themselves from predators in the forest.
