1.
A person's diet contains examples of food rich in protein, fat, vitamins, mineral ions, fiber, and water. Which of the following types of food would be a healthy addition to the diet to make it balanced?
Correct Answer
D. Pasta
Explanation
Pasta would be a healthy addition to the diet to make it balanced because it is a good source of carbohydrates and provides energy. It is also low in fat and contains fiber, which aids in digestion. While eggs and steak are rich in protein, they may also be high in saturated fat. Butter is high in fat and not a good source of essential nutrients. Therefore, pasta would be a better choice to ensure a balanced diet.
2.
The level of cholesterol in the body does not depend on
Correct Answer
A. The activity of the pancreas
Explanation
The level of cholesterol in the body does not depend on the activity of the pancreas because the pancreas is primarily responsible for producing and releasing digestive enzymes and hormones such as insulin, which regulate blood sugar levels. Cholesterol levels are mainly influenced by factors such as genetics, liver function, and diet. The liver produces cholesterol and regulates its levels in the body, while diet plays a significant role in determining the amount of cholesterol consumed.
3.
Which one of the following has the highest metabolic rate?
Correct Answer
C. Muscular male
Explanation
Muscular male has the highest metabolic rate because muscle tissue requires more energy to maintain compared to fat tissue. Muscles are metabolically active and require more calories to function, even at rest. Therefore, a muscular male with a higher muscle mass will have a higher metabolic rate compared to the other options listed.
4.
Which type of fat is present in healthy diets?
Correct Answer
D. Poly-unsaturated fat
Explanation
Poly-unsaturated fat is present in healthy diets because it is considered a healthy type of fat. It is found in foods such as fish, nuts, seeds, and vegetable oils. Poly-unsaturated fats are beneficial for heart health as they can help lower cholesterol levels and reduce the risk of heart disease. They also contain essential fatty acids that the body needs but cannot produce on its own. Including poly-unsaturated fats in a balanced diet can contribute to overall health and well-being.
5.
The term used to describe how fast chemicals reactions take place in the body
Correct Answer
D. Metabolic rate
Explanation
Metabolic rate refers to the speed at which chemical reactions occur in the body. It is a measure of the energy expenditure and is influenced by factors such as age, gender, body composition, and physical activity level. This rate is important for various physiological processes, including digestion, respiration, and circulation. Therefore, the term "metabolic rate" accurately describes the speed at which chemical reactions take place in the body.
6.
Which two of the following has the highest energy demand?
Correct Answer(s)
B. Pregnant person
C. Active person
Explanation
The pregnant person and the active person have the highest energy demand compared to the obese person and the teacher. During pregnancy, a woman's body needs extra energy to support the growth and development of the fetus. Similarly, an active person who engages in regular physical activity requires more energy to fuel their muscles and maintain their overall fitness. In contrast, an obese person may have a higher body weight but their energy demand may be lower due to reduced physical activity and metabolic factors. A teacher's energy demand would depend on their level of physical activity and lifestyle choices.
7.
Which of the following conditions is not a consequence of obesity?
Correct Answer
C. Liver failure
Explanation
Liver failure is not a consequence of obesity. While obesity can lead to various health conditions such as arthritis, high blood pressure, and heart disease, it does not directly cause liver failure. Liver failure is usually associated with other factors such as excessive alcohol consumption, viral hepatitis, or certain medications. However, obesity can contribute to non-alcoholic fatty liver disease (NAFLD), which is a condition characterized by excessive fat buildup in the liver, but it does not necessarily lead to liver failure.
8.
The best definition of metabolic rate is
Correct Answer
B. The activity of chemical reactions in the body over time
Explanation
Metabolic rate refers to the activity of chemical reactions in the body over time. It is a measure of how efficiently the body converts food into energy and performs various physiological processes. It involves the breakdown of nutrients, such as carbohydrates and fats, to produce energy and the synthesis of molecules needed for growth and repair. The metabolic rate can vary among individuals and is influenced by factors such as age, gender, body composition, and physical activity level.
9.
A man weighs 100 stones. He is likely to suffer which of the following collection of conditions?
Correct Answer
D. Obesity, diabetes, high blood pressure
Explanation
Given that the man weighs 100 stones, it is safe to assume that he is extremely overweight, which indicates obesity. Obesity is often associated with an increased risk of developing diabetes and high blood pressure. Therefore, the collection of conditions that the man is likely to suffer from is obesity, diabetes, and high blood pressure.
10.
Which of the following are foods likely to be found in a healthy balanced diet?
Correct Answer
B. Carbohydrates, minerals, vitamins, proteins
Explanation
The correct answer is carbohydrates, minerals, vitamins, proteins. A healthy balanced diet should include carbohydrates for energy, minerals for proper bodily functions, vitamins for overall health and wellbeing, and proteins for growth and repair of tissues.
11.
The healthy range of BMI is
Correct Answer
B. 20 - 30
Explanation
The healthy range of BMI is 20-30 because this range is considered normal and indicates a healthy weight for most adults. A BMI below 20 may indicate being underweight, while a BMI above 30 may indicate being overweight or obese. Therefore, a BMI between 20 and 30 is generally considered to be within a healthy range.
