A
Carbohydrates
B
Protein
C
Fat
D
Vitamins

A
Increase heart rate
B
Improve flexibility and prevent injury
C
Build muscle strength
D
Reduce blood pressure
Answer: b) Improve flexibility and prevent injury. Stretching before exercise helps to loosen muscles and increase flexibility, reducing the risk of injury during physical activity. Increasing heart rate, building muscle strength, and reducing blood pressure are not the primary goals of pre-exercise stretching.
A
Weightlifting
B
Swimming
C
Sprinting
D
Yoga
Answer: b) Swimming. Aerobic exercises, also known as cardiovascular exercises, involve continuous movement of large muscle groups and increase the heart rate. Swimming is an excellent example of aerobic exercise. Weightlifting, sprinting, and yoga primarily focus on strength, speed, and flexibility, respectively.
A
Increased stress levels
B
Improved cognitive function and mood
C
Reduced hydration
D
Enhanced muscle recovery
Answer: b) Improved cognitive function and mood. Sufficient sleep is essential for brain health, supporting cognitive function, mood regulation, and overall well-being. Increased stress levels, reduced hydration, and enhanced muscle recovery are not the primary benefits of sleep.
A
Saturated fat
B
Unsaturated fat
C
Trans fat
D
Cholesterol

A
Digesting food
B
Transporting oxygen
C
Regulating body temperature
D
Protecting the body against infection and illness

A
Once a week
B
Daily
C
Every other week
D
2-3 times a week

A
Distance
B
Weight lifted
C
Duration
D
Heart rate
