Questions and Answers

1.

If all minerals were extracted from the human body, they would weigh approximately 5 pounds.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The human body contains various minerals such as calcium, phosphorus, potassium, and iron, among others. These minerals are essential for the proper functioning of the body. While the exact weight may vary from person to person, it is estimated that the total weight of minerals in the human body is around 5 pounds. This is due to the fact that minerals are present in bones, teeth, muscles, and other tissues. Therefore, the statement that all minerals extracted from the human body would weigh approximately 5 pounds is true.

Without water, a person can survive for around two weeks.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The statement is false. Without water, a person can only survive for a few days, typically around three to five days. Water is essential for various bodily functions, such as regulating body temperature, transporting nutrients, and removing waste. Dehydration can lead to severe health complications and ultimately death if not addressed promptly. Therefore, it is crucial to consume an adequate amount of water regularly to maintain proper hydration levels.

Magnesium is important for the heart muscles.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Magnesium is indeed important for the heart muscles. It plays a crucial role in maintaining a healthy heart rhythm and regulating blood pressure. Magnesium helps relax and dilate the blood vessels, allowing for better blood flow to the heart. It also helps prevent the accumulation of calcium in the arteries, reducing the risk of heart disease. Additionally, magnesium helps maintain proper electrical conduction in the heart, ensuring that it beats regularly and efficiently. Therefore, it is true that magnesium is important for the heart muscles.

Which of the following prevents pernicious anaemia?
- A.
  
  Copper
- B.
  
  Cobalt
- C.
  
  Iron
Correct Answer
B. Cobalt

Explanation
Cobalt prevents pernicious anaemia. Pernicious anaemia is a type of anaemia caused by a deficiency in vitamin B12. Cobalt is an essential component of vitamin B12, which is necessary for the production of healthy red blood cells. Without sufficient cobalt, the body cannot produce enough vitamin B12, leading to pernicious anaemia. Copper and iron do not play a direct role in preventing pernicious anaemia.

5.

The more alkaline a soil is, the more manganese can be found in it.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The statement is false because the more alkaline a soil is, the less manganese can be found in it. Manganese availability decreases as soil pH increases. So, acidic soils tend to have higher levels of manganese, while alkaline soils have lower levels.

Selenium should be taken with vitamin C.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
There is no scientific evidence or recommendation that suggests taking Selenium with vitamin C. While both Selenium and vitamin C are essential nutrients, they have different functions and can be obtained from a balanced diet. It is important to maintain a varied and balanced diet to ensure adequate intake of all essential nutrients, including Selenium and vitamin C, but there is no specific requirement to take them together. Therefore, the statement that Selenium should be taken with vitamin C is false.

Which of the following is an assimilation barrier to zinc?
- A.
  
  Alcohol
- B.
  
  Moisture
- C.
  
  Smoking
Correct Answer
A. Alcohol

Explanation
Alcohol is an assimilation barrier to zinc because it inhibits the absorption of zinc in the body. Alcohol interferes with the normal digestive process and can damage the lining of the digestive tract, which reduces the ability of the body to absorb nutrients, including zinc. Additionally, alcohol can increase the excretion of zinc through urine, further reducing its availability for absorption. Therefore, consuming alcohol can hinder the body's ability to effectively assimilate and utilize zinc.
