    Dwarfism=> condition of growth retardation resulting in abnormally short adult stature and caused by a variety of hereditary and metabolic disorders. While
    Cretinism=> is a condition of dwarfism and mental retardation arising due to the deficiency of thyroid hormone.
    Therefore, it is a condition caused due to congenital thyroid deficiency. Cretinism is present at birth, mostly due to maternal iodine deficiency.

    Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

    Dan Macmillan   Posted on 2 years ago

    it is the respiratory reaction that yield energy for the cell

    I think you have not written it well there i have never seen the word like that

    William Johnstone   Posted on 2 years ago

    Did you mean histamine?
    Histamine - a chemical found in some of the body's cells - causes many of the symptoms of allergies, such as a runny nose or sneezing. When a person is allergic to a particular substance, such as a food or dust, the immune system mistakenly believes that this usually harmless substance is actually harmful to the body.
