2. Moderately active occupations required:

Need or use 900 kcals per 8 hours

Need or use 1200 kcals per 8 hours

Need or use 1800 kcals per 8 hours

The answer is "Need or use 1200 kcals per 8 hours." This is because moderately active occupations require a moderate amount of energy expenditure, which is approximately 1200 kcals per 8 hours. This level of activity is higher than occupations that require 900 kcals per 8 hours but lower than occupations that require 1800 kcals per 8 hours. Therefore, the correct answer is 1200 kcals per 8 hours.

Explanation

The answer is "Need or use 1200 kcals per 8 hours." This is because moderately active occupations require a moderate amount of energy expenditure, which is approximately 1200 kcals per 8 hours. This level of activity is higher than occupations that require 900 kcals per 8 hours but lower than occupations that require 1800 kcals per 8 hours. Therefore, the correct answer is 1200 kcals per 8 hours.

3. Metabolism is defined as "The sum of all of the changes that occur as a result of chemical processes occurring in the body"

True

False

Metabolism refers to the collective set of chemical processes that take place in the body, resulting in various changes. These processes include the conversion of food into energy, the synthesis of molecules, and the breakdown of substances. Therefore, the given statement accurately defines metabolism as the sum of all changes occurring due to these chemical processes in the body. Hence, the answer is true.

4. The six nutrient groups includes: (Select four)

Protein

Carbohydrates

Fats

Acids

The six nutrient groups include protein, carbohydrates, and fats. These three macronutrients are essential for providing energy and supporting various bodily functions. Proteins are important for building and repairing tissues, while carbohydrates are the body's main source of energy. Fats also provide energy and help with the absorption of certain vitamins. Acids are not one of the six nutrient groups, so they are not included in the correct answer.

5. Match the following statements:

is “the amount of heat energy required to raise the temperature of 1 gram of water from 14o to 15o C.”

is “the amount of heat it takes to raise the temperature of a litre of water by one degree centigrade.”

6. Match the following statements:

Chemical reactions in the body that help break down complex compounds to simpler ones.

Chemical reactions that combine a number of simple molecules together to make more complex ones

The minimum rate at which energy is used to maintain its functions

Submit

7. The shell temperature is the temperature maintained in those structures below the skin and subcutaneous tissue.

True

False

The shell temperature is not the temperature maintained in structures below the skin and subcutaneous tissue. The shell temperature refers to the temperature of the external surface of an object or organism. It is the temperature that can be measured or felt from the outside.

The shell temperature is not the temperature maintained in structures below the skin and subcutaneous tissue. The shell temperature refers to the temperature of the external surface of an object or organism. It is the temperature that can be measured or felt from the outside.

8. The kilojoule is the metric unit of measurement for heat and energy.

True

False

The explanation for the given correct answer is that the kilojoule is not the metric unit of measurement for heat and energy. The correct metric unit for heat and energy is the joule. The kilojoule is a derived unit of measurement that is equal to 1000 joules. Therefore, the statement is false.

Explanation

The explanation for the given correct answer is that the kilojoule is not the metric unit of measurement for heat and energy. The correct metric unit for heat and energy is the joule. The kilojoule is a derived unit of measurement that is equal to 1000 joules. Therefore, the statement is false.

9. Food will provide the body with some of the fuel required for all its' activities.

True

False

Food does provide the body with fuel for its activities, but it is not the only source of fuel. The body also uses stored energy in the form of fat and glycogen. Additionally, the body can produce energy through processes like gluconeogenesis and ketogenesis. Therefore, while food is an important source of fuel, it is not the only source, making the statement false.

10. The body consists of the following nutrients: (Select five)

Protein 15-20%

Fat 4 - 7%

Carbohydrates 1%

Minerals and trace elements 4 - 5%

Water 65 - 70%

Vitamins insignificant amounts

The body consists of various nutrients, including protein, fat, carbohydrates, minerals and trace elements, and water. Protein makes up 15-20% of the body, providing essential amino acids for growth and repair. Fat contributes 4-7% of the body's composition, serving as a concentrated source of energy and insulation. Carbohydrates make up 1% of the body and are the primary source of energy. Minerals and trace elements, comprising 4-5% of the body, are crucial for various bodily functions. Water, constituting 65-70% of the body, is essential for maintaining hydration and facilitating various physiological processes. Vitamins are present in insignificant amounts in the body.
