Electromagnets can easily be turned on and off.
Explanation:
An electromagnet produces magnetic field which is done by the electric current. These electromagnets contain a wire would like a coil. The current passes through the wire and the magnetic field is concentrated in the center which is the "center of the coil".
When the current is "turned off" the magnetic field "disappears". This shows that we have can have a control over the passage of current or the magnetic field. Thus, the "main advantage" of the electromagnet is that it can be easily turned on and off whenever necessary.

Answer:
<em>What is the role of alveoli in respiration ⇔ Alveoli are the place where the exchange of gases takes place. The outer part of alveoli has blood vessels. These vessels are carrying Co2 rich blood to exchange at the alveoli. The O2 from the alveoli is diffused into the blood while co2 is sent into the lungs. That O2 rich blood is then carried to heart to pump it to the whole body. and this process continues. </em><em>The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.</em>

Answer:
65 L
Explanation:
It is assumed that the temperature is constant at both the sea level and the altitude.
<em>According to the gas law, at constant temperature, the pressure of a gas is inversely proportional to its volume.</em> Mathematically:
P1V1 = P2V2 where P1 = pressure at initial volume, V1 = volume at initial pressure, P2 = pressure at final volume, and V2 = volume at final pressure.
In the illustration, V1 = 15 L, P1 = 100 kPa, V2 =?, P2 = 23 kPa
V2 = P1V1/P2 = 100 x 15/23 = 65.22 L
<u>The volume of the hot air balloon at the altitude would be 65 L</u>
