The answer for this is ricket.
Ricket happens because there is a lack of calcium absorption, and vitamin d has effects on this because vitamin d helps the absorption of calcium. Calcium is a kind of mineral necessary for human body as it can strengthen bones and teeth. Lack of these can lead to soft bones, and especially in children, they may get ricket. Ricket is where the legs bend outwards.
Aside from rickets, there may be other possible deficiency symptoms and diseases such as weak muscles and pain.

<u>random mutations:</u>
What is commonly called "random mutation" does not in fact occur in a mathematically random pattern. The process of genetic mutation is extremely complex, with multiple pathways, involving more than one system. Current research suggests most spontaneous mutations occur as errors in the repair process for damaged DNA.

the activity or condition of competing.
<u>environmental changes:</u>
Examples of these global environmental changes include climate change, freshwater shortages, loss of biodiversity (with consequent changes to functioning of ecosystems), and exhaustion of fisheries.
