Examples of Nutritional Deficiency are

A. continually divide throughout life: This describes labile cells (e.g., epithelial cells of skin, GI tract) - not facultative mitotic cells.
B. kidney cells are facultative mitotic cells: Many renal epithelial cells (e.g., tubular cells) are stable/facultative - they do not constantly divide but can re-enter the cell cycle after injury.
C. replaced by fibrous scarring after trauma: If injury is severe and regeneration fails, even facultative cells may be replaced by scar tissue, but this is not the defining property of facultative mitotic cells.
D. divide when required: Correct description of facultative (stable) cells - they remain quiescent normally but divide when needed (e.g., after injury).
E. Two answers are correct: Both B and D are correct statements about facultative mitotic cells.
F. None are correct: Some choices (B and D) are correct.

A. hay fever: Hay fever (allergic rhinitis) is a classic Type I (IgE-mediated) hypersensitivity reaction.
B. eczema: Atopic eczema/dermatitis is commonly associated with Type I (IgE-mediated) hypersensitivity in atopic individuals (though it’s multifactorial) - therefore it can be a Type I example.
C. anaphylaxis: Anaphylaxis is the extreme systemic form of Type I hypersensitivity (IgE-mediated).
D. glomerulonephritis: Many forms of glomerulonephritis are immune complex–mediated (Type III) or antibody-mediated (Type II), not Type I IgE-mediated hypersensitivity.
