Answer:
c) Isometric
Explanation:
Isometric contraction is one where the muscle develops tension, but there is no change in its external length. In other words, isometric contraction is one in which the muscle contracts and produces force without any macroscopic changes in the joint angle. This is when we try to lift an object much heavier than we can handle, as the cheerleader shown in the question above tried to do. It seems that the mechanism of this contraction lies in the fact that the energy that would normally be exhibited as external mechanical work is used in the structural rearrangement of the fibers, ie the fibers shorten and the tendon lengthens, and some of the energy dissipates into heat. .
Answer:
I think it is probably (C) for the first one because some take a higher dose to get a stronger effect. At least from my experience :/
And for 9 I would say taking two little (D) because that should not pose a harm for a under-dose
Hope this helps

Answer:
When we smoke the smoke of the cigarette contains nicotine compounds which get into our lungs and from there it makes it's way into our blood stream. This causes constriction of our blood vessels when the diameter of our blood vessels becomes less the area through which the blood travels becomes less than healthy vessels thus the blood has to travel with greater velocity to maintain the same flow of nutrients and oxygen to the tissues of our body. The faster moving blood exerts a greater force on the walls of the vessels of our body thus the pressure of blood increases.
Arteries are the type of blood vessels that are affected by nicotine smoking.
