A. Mercury

B. Pluto

C. Neptune

D. Uranus

The planets in the solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and possibly Planet Nine, in that order, starting from the planet closest to the sun and moving outward.The eighth and farthest planet from the Sun is Neptune. It is the third most massive, the densest big planet, and, in terms of diameter, the fourth largest planet in the Solar System. It is little more massive than its near-twin Uranus, with 17 times the mass of Earth. Because of its larger mass and the increased gravitational compression of its atmosphere, Neptune is both physically smaller and denser than Uranus. Its principal constituents are gasses and liquids, so it lacks a definite solid surface.

2. Severe deficiency of vitamin D results in ______.

A. Scruvy

B. Rickets

C. Night blindness

D. None of these

Explanation:-

For a person to be healthy and happy generally, vitamin D is essential. Although most people are aware of vitamin D, commonly known as the “sunshine” vitamin, many are either uninformed of all the health benefits it naturally offers or don’t know how to improve their consumption. Furthermore, a lot of individuals are unaware of the potential risks associated with vitamin D deficiency, an unpleasant but widespread condition that many people unknowingly suffer from as a result of insufficient sun exposure and dietary vitamin D sources. Children with rickets have softening and weakening of the bones, which is typically caused by a significant and protracted vitamin D deficit. Rare genetic disorders can potentially result in rickets. The body absorbs calcium and phosphorus from diet more easily when vitamin D is present.
