Positive energy balance is:.1. the state when energy expenditure exceeds energy intake. 2. a sign of weight loss. a desired state for good health. 3. the state when energy intake and energy expenditure are the same. 4. the state when energy intake exceeds energy expenditure.

The answer is option 4. the state when energy intake exceeds energy expenditure.

Explanation:

Energy balance is achieved when energy intake equals energy expenditure which results in minimal changes in the body's store of energy. This results in a stable body weight. Energy balance can be positive or negative. A positive energy balance occurs when calorie intake exceeds energy expenditure which results in gain in body weight. This is important for growing and pregnant animals for the purpose of synthesis of new tissues and fetal development. A negative energy balance occurs when calorie intake is below energy expenditure resulting in loss of energy from the body's energy stores. During negative energy balance there is weight loss and decreases in both fat and stores of lean body tissue.

Answer is option 4) the state when energy intake exceeds energy expenditure.

Refer below for the explanation.

Explanation:

Therefore,

Positive energy balance is: the state when energy intake exceeds energy expenditure.

Positive energy happens where there is caloric exceeds energy.

17 ft.

Step-by-step explanation:

We have been given that Carl dives in and touches the bottom of the pool, 15 feet below the surface of the water.

The elevation of Carl's hand would be .

Cameron is standing on a diving platform 2 feet above the surface. The elevation of Cameron's feet would be .

The vertical distance between Carl's hand and Cameron's feet would be difference of both altitudes.

Therefore, the vertical distance between Carl's hand and Cameron's feet is 17 ft.
