What is a pituitary gland
Bar graphs show patterns in data with variables that change over time; Whereas pie charts, show data as parts out of a whole, (such as 100%).
Answer:
The correct answer will be option-
1. UV light strikes the skin and converts a steroid molecule into an inactive form of vitamin D.
2. Inactive vitamin D is transported to the liver where it is modified.
3. Vitamin D is activated under the influence of PTH.
4. Inactive, chemically altered vitamin D is transported to the kidneys.
Explanation:
Vitamin D is a fat-soluble metabolite which helps maintain the health of the bone by maintaining the calcium homeostasis.
The vitamin D is synthesized mainly in the liver and kidney from the biologically inactive precursor of vitamin D called ergocalciferol and Cholecalciferol.
The inactive vitamin is synthesized in the skin when the skin is exposed to UV rays. The UV rays convert the 7-dehydrocholesterol, a steroid molecule to Vitamin D3, This inactive vitamin is then transported to the liver where it is converted to 25-hydroxyvitamin D.
This vitamin D form is further metabolized in the kidney controlled and regulated by the Parathyroid glands.
Does not absorb moistures: Man-made fibres do not absorb sweat, trapping heat in our body. Rough feel: Man-made fibres may give the rough feel, making it unsuitable for pyjamas, underwear, etc. Some individuals are often prone to skin allergy, because of the dermatological action of Man-made fibres.
