Dancing is a physical activity which strengthens the abdominal and calf muscles as well as improves flexibility.
<h3>What is a physical activity?</h3>
A physical activity is any activity which involves movement of the body in order to strengthen the muscles and to be physically fit.
Dancing is a physical activity which involves intricate and repeated movements of the body.
Dancing is beneficial because;
- it helps to relieve stress
- it improves flexibility
- it builds muscle endurance
Some muscles involved in dancing include;
- The abdominal muscles
- The quadriceps
- the glutes
Some risks in dancing include muscle injuries, dislocations and possibly fractures due to falls.
Therefore, a dancing routine strengthens the abdominal and calf muscles as well as improves flexibility.

<u>Answer:</u> The final equation has hydroxide ions which indicate that the reaction has occurred in a basic medium.
<u>Explanation:</u>
Redox reaction is defined as the reaction in which oxidation and reduction take place simultaneously.
The oxidation reaction is defined as the reaction in which a chemical species loses electrons in a chemical reaction. It occurs when the oxidation number of a species increases.
A reduction reaction is defined as the reaction in which a chemical species gains electrons in a chemical reaction. It occurs when the oxidation number of a species decreases.
The given redox reaction follows:

To balance the given redox reaction in basic medium, there are few steps to be followed:
- Writing the given oxidation and reduction half-reactions for the given equation with the correct number of electrons
Oxidation half-reaction: 
Reduction half-reaction: 
- Multiply each half-reaction by the correct number in order to balance charges for the two half-reactions
Oxidation half-reaction:
( × 3)
Reduction half-reaction:
( × 2)
The half-reactions now become:
Oxidation half-reaction: 
Reduction half-reaction: 
- Add the equations and simplify to get a balanced equation
Overall redox reaction: 
As we can see that in the overall redox reaction, hydroxide ions are released in the solution. Thus, making it a basic solution
Answer:
중요하지 않은 것들의 예로는 생각, 감정, 빛, 에너지가 있습니다. ... 에너지 : 빛, 열, 운동 및 위치 에너지, 소리는 질량이 없기 때문에 물질이 아닙니다. 사물
Explanation:
Energy: Light, heat, kinetic and potential energy, and sound are non-matter because they are massless. Objects that have mass and are matter may emit energy.
