Explanation

Vitamin D toxicity, also called hypervitaminosis D.

It causes hypercalcemia and renal failure.

Daily Vitamin D requirement is 200–600 IU.

While skin produces up to 10,000 IU after full UV exposure.

Explanation

• Exposure to sunlight triggers the production of vitamin D in the skin.
• Specifically, ultraviolet B (UVB) rays from the sun interact with a compound called 7-dehydrocholesterol, converting it into vitamin D3 (cholecalciferol).
• Vitamin D is essential for calcium absorption, bone health, and immune system regulation.

Explanation

The human hand has 27 bones:

the carpals or wrist accounts for 8

the metacarpals or palm contain five

the remaining fourteen are digital bones; fingers and thumb.

while 

The number of bones in a human skull is 22

300 bones are there in a newly born infant.

Because the brain is so rich in nerve cells, or neurons, it is the most energy-demanding organ, using one-half of all the sugar energy in the body.

Explanation

Selenium works in conjunction with Vitamin E as an antioxidant, helping to protect cells from oxidative damage.

This "sparing effect" means that adequate selenium reduces the need for Vitamin E by enhancing its antioxidant function in the body.

Explanation

One of the early signs of vitamin A deficiency is night blindness (nyctalopia).

while

Vitamin K deficiency leads to uncontrolled bleeding during an injury

A deficiency of Vitamin D results in Rickets
