1. The change in a baby's skin color as they grow up is primarily due to increased melanin production. Melanin is the pigment responsible for the color of our skin, hair, and eyes. When babies are born, they commonly have lighter or pinkish skin tones because their melanin production is not fully developed. As they age and are exposed to sunlight and other environmental factors, their melanin production increases, leading to a darker skin color.
2. Nails have the ability to regenerate because of the presence of specialized cells in the nail matrix, which is located near the base of the nail. When the nail is injured or completely removed, these cells undergo rapid division and differentiation to produce new nail cells. This process is similar to how our skin regenerates when it is injured. As the new cells grow and multiply, they gradually push out towards the tip of the finger or toe, eventually forming a new nail. The regeneration of the entire nail usually takes several weeks or months, depending on the individual's overall health and the extent of the injury.

A certain boy aged 14 years old was an orphan and he had black skin color after adopted by a certain donor his color skin change to be litter than before .Explain what cause to his skin color to change?
A change in skin color can occur due to several factors, including genetics, environment, and exposure to sunlight. In the scenario you described, it is important to recognize that skin color is primarily determined by the amount of melanin production in the skin.
When a person is adopted, their environment and lifestyle may change. If the boy's new environment had less exposure to sunlight or if he started using sun protection measures such as sunscreen, it could result in a lighter skin color over time. Sunlight exposure plays a significant role in stimulating melanin production. Less exposure to sunlight may lead to a reduction in melanin production, resulting in a lighter complexion.
It's also worth considering that genetics play a crucial role in determining skin color. If the boy and his adoptive family have different genetic backgrounds, it is possible that he may have inherited genes that are associated with lighter skin tones.
However, it is important to note that these changes in skin color are gradual and could take a significant amount of time. It is essential to embrace and appreciate the diversity of skin colors and to avoid making assumptions or judgments based on someone's appearance.
