Answer:

hey mate here is your answer

. Iodine is used in table salt to prevent Goitre.

Explanation:

more explanation:

. Vitamin D deficiency in young children causes rickets which is characterised by muscles weakness, pain, fractures and delayed motor development. This makes option A incorrect. Scurvy, caused by vitamin C deficiency, is characterized by scaly skin, muscle degeneration and gum bleeding. Option B is incorrect. Thyroxine and triiodothyronine are thyroid hormones which target all tissues and stimulate metabolic rate, growth and development. Thyroxine has four iodine atoms while triiodothyronine has three iodine atoms. The dietary iodine serves as source and thus iodine deficient diet renders the gland unable to synthesize the hormones. Under these conditions, constant stimulation of thyroid gland by anterior pituitary to secrete hormones leads to enlargement of thyroid gland; the simple goiter. Appropriate dietary iodine intake prevents formation of goiter which makes option C correct. Overproduction of GH in adults causes acromegaly, characterized by enlargement of feet, hands and face (specially the chin, nose and eyebrows ridges) as long bones do not respond to the hormone in them.

. Iodised salt (also spelled iodized salt) is table salt mixed with a minute amount of various salts of the element iodine. The ingestion of iodine prevents iodine deficiency. Worldwide, iodine deficiency affects about two billion people and is the leading preventable cause of intellectual and developmental disabilities.[1][2] Deficiency also causes thyroid gland problems, including endemic goitre. In many countries, iodine deficiency is a major public health problem that can be cheaply addressed by purposely adding small amounts of iodine to the sodium chloride salt.

. Iodine is a micronutrient and dietary mineral that is naturally present in the food supply in some regions, especially near sea coasts but is generally quite rare in the Earth's crust since iodine is a so-called heavy element, and abundance of chemical elements generally declines with greater atomic mass. Where natural levels of iodine in the soil are low and the iodine is not taken up by vegetables, iodine added to salt provides the small but essential amount of iodine needed by humans.
