-Grams of protein

Accepted Answer

Grams of protein are a measure of the amount of protein consumed in a diet, and are typically considered as part of overall energy intake.

Answer: C
 Consuming more protein, along with a reduced-calorie diet or increased physical activity, may help with weight loss.

Answer: D
 This equation is used to estimate daily calorie needs for healthy adults based on age, sex, weight, and physical activity level. It does not directly relate to grams of protein intake or weight loss.

Question 2

As core body temperature rises,thermal injury occurs.

Accepted Answer

As core body temperature rises, thermal injury can occur due to damage to the body's cells and tissues. This can result in heat exhaustion or heat stroke, which can be life-threatening. It is important to take measures to prevent overheating and to seek medical attention if symptoms of heat-related illness occur.

Question 3

Central adiposity indicates subcutaneous fat.

Accepted Answer

Central adiposity refers to the accumulation of fat around the abdominal organs (visceral fat) rather than subcutaneous fat, which is found just under the skin.

-Cell

Accepted Answer

A cell is the most basic unit of life.

Answer: D
 A change in inheritable genetic traits is called a mutation, which can occur in a cell.

Answer: C
 Hypothesis-driven research is research that is designed to test a specific hypothesis, and can involve the study of cells.

Answer: A
 The range of body weight that is easy to maintain is referred to as the set point, which can be regulated by cells in the body. However, this answer is not directly associated with the term "cell" and could be considered a less relevant choice.

Question 5

One pound of body fat weighs more than one pound of lean body mass.

Accepted Answer

This statement is a trick question as one pound is always equal to one pound regardless of what it is weighing, so both one pound of body fat and one pound of lean body mass weigh the same amount. The difference between the two is the volume or space they take up, as fat is less dense than muscle.

-Fat mass

Accepted Answer

Fat mass is the amount of stored energy in the body.

Answer: C
 Weight loss involves decreasing the amount of fat mass in the body.

Answer: D
 This equation is used to calculate total daily energy expenditure, which is important in managing body weight and fat mass.

-Aerobic exercise

Accepted Answer

Aerobic exercise is any activity that raises your heart rate and breathing rate, such as jogging.

Answer: C
 Aerobic exercise is typically done at a moderate intensity, which is between 70 to 85% of your maximum heart rate.

Answer: B
 Weight lifting is not considered aerobic exercise because it typically does not raise your heart rate and breathing rate to the same level as aerobic exercise.

Answer: D
 Yoga can have some aerobic benefits, but it is not typically done at a high enough intensity to be considered aerobic exercise.

-Calories burnt

Accepted Answer

Calories burnt can be calculated using the formula: Hours x Resting Energy Expenditure (REE) x activity factor divided by 24.

-Evolution

Accepted Answer

Evolution refers to the change in inheritable genetic traits over time through natural selection and other mechanisms.

Question 11

The pre-exercise meal should be rich in protein.

Accepted Answer

The pre-exercise meal should primarily consist of carbohydrates to provide energy, with moderate protein and low fat for easier digestion and energy utilization.

-Resistive exercise

Accepted Answer

Resistive exercise refers to exercises that use weights or resistance to build strength, such as weight lifting.

Answer: D
 Yoga involves using body weight and resistance to build strength and improve flexibility, making it a form of resistive exercise.

Answers A and C are incorrect as they do not involve resistive exercise. Jogging is a form of aerobic exercise, while 70-85% of MHR refers to the target heart rate zone for aerobic exercise.

-Negative energy balance
Answers:

Accepted Answer

Negative energy balance occurs when energy intake is less than energy expended, resulting in weight loss.

Answer: B
 Energy intake refers to the amount of energy consumed through food and beverages.

Answer: D
 This formula is used to calculate daily energy expenditure, taking into account resting energy expenditure (REE) and physical activity level, which can be useful for determining energy balance.

Answer: A
 Stored energy refers to energy that is stored in the body in the form of fat tissue, which can be used as a source of energy when energy intake is insufficient.

Question 14

As the intensity of the exercise increases,so does the percentage of carbohydrate used to produce ATP.

Accepted Answer

As the intensity of exercise increases, the body relies more on carbohydrates as a fuel source to produce ATP. During low-intensity exercise, the body predominantly uses fats as the primary energy source. However, during high-intensity exercise, the body relies more on carbohydrates as they can be broken down quickly and efficiently to produce ATP.

-Set point

Accepted Answer

Set point refers to the range of body weight that is easy to maintain, meaning that the body can easily regulate and maintain weight within this range.

Answer: C
 Research that is hypothesis-driven is often referred to as hypothesis testing research, which is a type of research that seeks to test a specific hypothesis or set of hypotheses.

Answer: D
 The change in inheritable genetic traits is called genetic variation, which refers to the differences that exist between individual members of a population. This variation is what allows for natural selection to occur.

Answer: B
 The most basic unit of life is the cell, which is the structural and functional unit of all living organisms.

Question 16

Spot reduction of body fat can be achieved with exercise.

Accepted Answer

Spot reduction is a myth. When we exercise, our body burns fat from all over the body and not just from a specific area. To reduce fat from a particular area, we need to lose overall body fat through a combination of proper nutrition and regular exercise.

Question 17

Essential fatty acids combined with amino acids support muscle glycogen repletion.

Accepted Answer

Essential fatty acids are crucial for many bodily functions, but they do not directly support muscle glycogen repletion. Glycogen repletion primarily depends on carbohydrate intake, not fatty acids or amino acids.

Question 18

A four-pound-per-week weight loss will cause the loss of lean body mass.

Accepted Answer

Losing four pounds per week is a very rapid weight loss and may result in the loss of both fat and lean body mass. The percentage of lean body mass lost may be higher if the weight loss is too rapid or if there is no exercise or resistance training incorporated into the weight loss program. It is recommended to aim for a gradual weight loss of 1-2 pounds per week to minimize the loss of lean body mass.

Question 19

One pound of body fat mass provides more Calories than one pound of lean body mass.

Accepted Answer

This is because body fat mass has a higher energy density than lean body mass. One pound of body fat provides about 3,500 Calories, while one pound of lean body mass provides only about 600-700 Calories.

Question 20

The body mass index is a weight-for-height calculation that is used to determine an interpretation of body weight.

Accepted Answer

The body mass index (BMI) is a weight-for-height calculation that is commonly used to classify individuals as underweight, normal weight, overweight, or obese.
