Metals are often associated with industrial use and construction, but many of them play a vital role in the human body and are essential for maintaining good health. These bio essential metals, present in small quantities, are involved in crucial physiological functions such as oxygen transport, enzyme activity, and immune response. Iron, for instance, is a key component of hemoglobin, the protein in red blood cells that carries oxygen throughout the body. A deficiency in iron can lead to anemia, fatigue, and reduced cognitive function. Zinc supports the immune system, aids in wound healing, and is necessary for proper growth and development, especially in children. Calcium, though more commonly known as a mineral, is technically a metal. It is essential for strong bones and teeth, and also plays a role in muscle contraction and nerve transmission. Similarly, magnesium contributes to over 300 enzyme reactions in the body and supports muscle and nerve function. Copper aids in the formation of red blood cells and supports cardiovascular health, while selenium, a trace metal, functions as an antioxidant, protecting cells from damage. However, it is important to note that while these metals are beneficial in small amounts, excessive intake either through supplements or environmental exposure can be toxic. Maintaining a balanced diet rich in fruits, vegetables, whole grains, and lean proteins typically provides sufficient amounts of these essential metals. Understanding their role highlights the intricate connection between nutrition, chemistry, and overall health.
Choose the correct interrogative form of the following sentence: “Copper aids in the formation of red blood cells.”
Does copper aid in the formation of red blood cells?
The sentence 'Copper aids in the formation of red blood cells' is a simple present-tense affirmative statement, and we must convert it into a question that keeps the same tense and meaning.
Simple present statements that have no auxiliary verb form questions with the helping verb 'do'. The helping verb must agree with the subject in number and person.
The subject 'Copper' is a singular, third-person, uncountable noun, so the correct present-tense form of the helper is 'does', not 'do'.
When 'does' is used, the main verb drops its -s inflection and returns to the bare form 'aid'. This gives 'Does copper aid in the formation of red blood cells?', which is option 3.
Option 1, 'Do copper aid...', wrongly uses the plural helper 'do' with a singular subject, so it breaks subject-verb agreement.
Option 2 shifts the tense to the present continuous ('Is copper aiding'), changing the original simple-present meaning.
Option 4 shifts the tense to the present perfect ('Has copper aided'), which again does not match the original simple present statement.
Only option 3 preserves the tense and observes correct agreement, so it is the right interrogative form.
Does copper aid in the formation of red blood cells?
