By adding these vegetables to his plate, Dominic is making a smart choice to support his recovery from the respiratory infection.

Exposure to sunlight allows the body to produce vitamin D because sunlight triggers a chemical reaction in the skin, converting a type of cholesterol into an inactive form of vitamin D. This inactive form is then converted into its active form in the liver and kidneys. Vitamin D is essential for maintaining healthy bones and teeth, as it helps the body absorb calcium and phosphorus from the diet. Therefore, it is true that the body can make vitamin D with exposure to sunlight.

If a vitamin is missing from the diet, deficiency symptoms will appear. Vitamins are essential nutrients that the body needs in small amounts to function properly. Each vitamin has specific functions in the body, and a deficiency of any particular vitamin can lead to a range of symptoms and health problems. These symptoms can vary depending on the specific vitamin that is lacking, but commonly include fatigue, weakness, impaired immune function, and various other health issues. Therefore, it is important to have a balanced diet that includes all the necessary vitamins to prevent deficiency symptoms.

Night blindness is a condition caused by a deficiency in vitamin A, where the cells in the eyes take longer to adjust to dim light. This leads to poor night vision, making it difficult for individuals to see in low-light conditions. The other options, beriberi, pellagra, and rickets, are unrelated conditions caused by deficiencies in other vitamins and nutrients.

Exposure to sunlight helps the body produce Vitamin D. Therefore, studying in a sunny spot a few times a week would allow the body to make enough Vitamin D. Vitamin A, Vitamin E, and Vitamin K are not produced by the body in response to sunlight.

Vitamins are actually considered to be essential nutrients. They are required by the body in small amounts for various vital functions, such as growth, development, and maintenance of overall health. The body cannot produce enough vitamins on its own, so they need to be obtained through the diet. Therefore, the statement that vitamins are nonessential nutrients is incorrect.

Provitamins are substances that can be converted by the body into active forms of vitamins. These compounds are usually found in food and undergo chemical reactions within the body to become biologically active vitamins. This conversion process allows the body to utilize these compounds as essential nutrients. Therefore, the statement "Provitamins are compounds the body can convert into active forms of vitamins" is true.

The correct answer emphasizes that taking megadoses of calcium is not necessary and can be harmful. It suggests that getting the right amount of calcium is sufficient for bone development and excessive intake can have negative consequences.

The answer "Dang Girl! You obviously know your vitamins! Good Job!" is the correct response because Sahmirah is making a wise decision by taking a Vitamin B-12 supplement. Since she eats very little meat, which is a primary source of Vitamin B-12, taking a supplement ensures that she is getting enough of this essential vitamin. The coach's statement that supplements are for losers and Sahmirah doesn't need to take a B-12 vitamin is incorrect and dismissive of Sahmirah's informed choice.

Iodized salt is a great way to avoid goiter because goiter is caused by a deficiency of iodine in the diet. Iodine is essential for the production of thyroid hormones, and when there is not enough iodine in the body, the thyroid gland enlarges in an attempt to compensate. By using iodized salt, which is salt that has been fortified with iodine, Dre'Shianna ensures that she is getting enough iodine in her diet, thereby reducing the risk of developing goiter.

The correct answer emphasizes that excessive doses of Vitamin A are not obtained from food but rather from supplements. This implies that Auriell's decision to limit foods rich in Vitamin A is unnecessary as she is unlikely to consume excessive amounts of the nutrient through her diet alone.

Perricious anemia is the correct answer because it is a deficiency disease caused by an inability to absorb vitamin B12. It is characterized by symptoms such as fatigue, weakness, a red and painful tongue, and tingling or burning in the skin.

A food that contains a certain vitamin precursor is a source of that vitamin only after the food is eaten and the vitamin is produced. This means that the food itself does not contain the vitamin in its active form, but rather contains a compound that can be converted into the active form of the vitamin once it is ingested and processed by the body. In this context, the term "precursor" refers to a substance that can be transformed into another substance, in this case, a vitamin.

The explanation for the answer being False is that deficiencies of pathogenic acid and biotin are not fairly common because these nutrients are found in only a limited number of food sources. Therefore, it is incorrect to say that deficiencies are fairly common.

Erythrocyte hemolysis is the correct answer because it refers to the condition of broken red blood cells, which is described in the question. This condition is often seen in premature babies and can result in weakness and listlessness.

Cutting foods into smaller pieces increases their surface area, which in turn increases their exposure to air and heat. This increased exposure can lead to higher vitamin losses as some vitamins are sensitive to air and heat. Therefore, it is true that cutting foods into smaller pieces can increase their exposure to vitamin losses.

Fat-soluble vitamins, unlike water-soluble vitamins, can be stored in the body for longer periods of time. This means that if excessive amounts of fat-soluble vitamins are consumed, they can accumulate in the body and reach toxic levels. This can have negative impacts on health as it can lead to vitamin toxicity, which can cause various symptoms and health problems.

The given statement is false. While vitamin C is commonly believed to help prevent the common cold, research does not provide conclusive evidence to support this claim. Some studies suggest that vitamin C may help reduce the duration or severity of cold symptoms, but it does not necessarily prevent people from getting the common cold altogether. Therefore, the statement is incorrect.

Canned green beans are likely to have higher vitamin content than fresh green beans that are not stored properly because the canning process helps to preserve the nutrients in the beans. Improper storage of fresh green beans can lead to nutrient loss over time. Canning ensures that the beans are sealed in an airtight container, protecting them from exposure to light, air, and moisture which can degrade vitamins. Additionally, the canning process involves heat treatment which can help to retain the nutrient content of the beans. Therefore, it is likely that canned green beans have higher vitamin content compared to fresh green beans that are not stored properly.

The given answer is correct because all of the other options provide examples of known interactions between nutrients. Potassium and sodium balance fluids in the cells, magnesium and calcium regulate blood clotting, and calcium, phosphorus, and vitamin D build teeth are all well-known interactions between nutrients. However, iodine and iron do not directly interact to make certain hormones.

Vitamin C is responsible for various functions in the body, including aiding in the healing of wounds and facilitating the absorption of iron. It is a crucial nutrient that supports the production of collagen, a protein that helps in the formation of new tissue and promotes wound healing. Additionally, vitamin C enhances the absorption of iron from plant-based sources, which is essential for the production of red blood cells and overall iron balance in the body.

Niacin is needed by every living organism because it is crucial in forming DNA. DNA is the genetic material that carries the instructions for the development, functioning, and reproduction of all living organisms. Niacin plays a vital role in the synthesis and repair of DNA, ensuring the proper functioning and growth of cells. Without niacin, organisms would not be able to effectively produce and maintain their genetic material, leading to various health issues and developmental problems. Therefore, niacin is an essential nutrient required by all living organisms.
