It receives signals from other parts of the body and adjusts the metabolic rate accordingly to maintain balance and energy homeostasis.
6.
Which of the following drinks produces empty calories?
Correct Answer
C. Beer

Therefore, it is considered to be a source of empty calories.
7.
What type of exercise combines rhythmic exercising with stretching and strength training?
Correct Answer
D. Aerobics
Explanation
Aerobics combines rhythmic exercising with stretching and strength training. It involves high-energy movements that increase heart rate and improve cardiovascular fitness. The combination of rhythmic movements, such as dance steps or aerobic routines, with stretching exercises and strength training exercises helps to improve flexibility, endurance, and muscle strength. This type of exercise is often done in a group setting and is popular for its ability to provide a full-body workout while being fun and engaging.
8.
What is the typical heart rate in a healthy adult?
Correct Answer
B. 60 - 80 bpm
Explanation
The typical heart rate in a healthy adult is 60-80 bpm. This range is considered normal for resting heart rate and indicates a healthy cardiovascular system. A heart rate below 60 bpm is considered bradycardia, while a heart rate above 80 bpm is considered tachycardia. Regular exercise and overall physical fitness can contribute to a lower resting heart rate within this range.
9.
Arrhythmia is the abnormality of what body function?
Correct Answer
B. Heart rate
Explanation
Arrhythmia refers to the abnormality of heart rate. It is a condition where the heart beats too fast, too slow, or irregularly.

11.
Sugars like glucose and fructose provide instant energy boosts that are known as what?
Correct Answer
C. Simple carbohydrates
Explanation

What type of triglycerides are liquid at room temperature?
Correct Answer
D. Oils
Explanation
Oils are the type of triglycerides that are liquid at room temperature. Triglycerides are a type of fat molecule composed of three fatty acids attached to a glycerol backbone. The structure of the fatty acids determines whether the triglyceride is solid or liquid at room temperature. Fats, on the other hand, are solid at room temperature due to their higher saturation level of fatty acids. Therefore, oils, which have a higher unsaturation level, remain liquid at room temperature.
14.
How many calories must a food have per serving to qualify as low calorie?
Correct Answer
C. 40 calories or less
Explanation

Multi-grain bread is always "whole-grain"?
Correct Answer
B. False
Explanation
The statement is false because multi-grain bread is not always "whole-grain". Multi-grain bread refers to bread that is made from multiple types of grains, which can include whole grains, refined grains, or a combination of both. Whole-grain bread, on the other hand, is made entirely from whole grains, which means that all parts of the grain, including the bran, germ, and endosperm, are retained. Therefore, while multi-grain bread can contain whole grains, it is not always "whole-grain".
