Final answer:
A deficiency disease can occur if vitamins are removed, which is true. Vitamins are crucial for various bodily functions, and deficiencies can lead to diseases like scurvy, rickets, and peripheral neuropathy.
Step-by-step explanation:
A deficiency disease can certainly occur if vitamins are removed; this statement is true. Vitamins are essential nutrients required in small quantities for a range of physiological functions, including growth, immunity, and metabolism. Our bodies cannot synthesize most vitamins, meaning they must be consumed through diet. When there is a lack of certain vitamins, a variety of deficiency diseases can manifest.
For example, vitamin B6 deficiency, though rare, can lead to issues like irritability, depression, and peripheral neuropathy. A deficiency in vitamin C prompts a disease known as scurvy, characterized by symptoms such as bleeding gums and delayed wound healing due to impaired collagen formation. Rickets is another deficiency disease caused by inadequate vitamin D, leading to improper bone development in children. Moreover, not getting enough vitamin A can cause poor vision and other health problems.
These examples illustrate the critical role that vitamins play in maintaining health, and the serious consequences that can arise from vitamin deficiencies.
