In the heart, the valves are located between atria and ventricles and between ventricles and arteries (option D).
<h3>What are valves in the heart?</h3>
Valves are membranous partitions which permit the passage of the contents of a vessel or cavity in one direction, but stop or control the flow in the opposite direction.
Valves in the heart enforce a one-way blood flow through the heart and separate atria from ventricles, and ventricles from the large arteries that leave them.
The four valves in the heart and their location is as follows:
- tricuspid valve: located between the right atrium and the right ventricle
- pulmonary valve: located between the right ventricle and the pulmonary artery
- mitral valve: located between the left atrium and the left ventricle
- aortic valve: located between the left ventricle and the aorta.
The valves between the atria and ventricles are called atrioventricular valves or cuspid valves while those at the bases of the large vessels leaving the ventricles are called semilunar valves.
Therefore, it can be said that the valves of the heart are located between atria and ventricles and between ventricles and arteries.

The correct answer is option B. According to Newton’s third law of motion, the balloon is pushed forward as the air is forced out.
Newton's third law of motion states that to every action there is an equal and opposite reaction. The same law will apply on the balloon. As the air is forced out of the balloon it will exert an opposite force on the balloon which will cause the balloon to be pushed forward. If the air would not have caused an opposite force on the balloon causing it to be pushed forward it would have remained static. But, reaction of the outgoing air pressure made the balloon to move forward.
Answer: A table can be read from left to right or from top to bottom. If you read a table across the row, you read the information from left to right. You can get the information about the graph like what its about or information about a survey
