Final answer:
A deficiency of vitamins in the diet can weaken the immune system and impair vision. Vitamin C deficiency can lead to scurvy, affecting collagen formation and causing swollen gums and weak bones.
Step-by-step explanation:
A deficiency of vitamins in the diet can have several negative effects on the body. For example, vitamin A deficiency can weaken the immune system and impair vision. Vitamin D deficiency can also weaken the immune system and increase the risk of infections. Vitamin C deficiency can lead to scurvy, which affects the formation of collagen and can result in swollen gums, delayed wound healing, and weak bones. Therefore, the correct answer is c) Weakened immune system.
When there is a deficiency of vitamins in the diet, it does not lead to increased resistance to infections, improved vision, or enhanced blood clotting. Instead, the correct answer to what occurs with a vitamin deficiency is c) Weakened immune system. Vitamins are essential for various bodily functions, and a lack of them can cause severe health issues.
For instance, vitamin A deficiency can impair the immune system's ability to fight off infections and contribute to anemia and visual impairments. Similarly, vitamin D plays a crucial role in general immunity and bone health, and its insufficiency has been linked with increased susceptibility to infections and potentially even cancer.
Vitamins B and C are important for maintaining eyesight and aiding in wound healing and blood clotting, respectively. In particular, a deficiency in vitamin C can result in scurvy, characterized by fragile blood vessels and poor wound healing due to inadequate collagen formation.
