Answer:
Skeletal system
Explanation:
The skeletal system is made up of all the bones, cartilage, and ligaments in the body. There are over 200 bones in the human skeleton, connected by joints which allow them to bend and rotate.
It protects the vital organs, gives our body form and structure, and allows us to move (or bust a move!)
To move, the skeletal system works with the muscles and nerves in the body.
Answer: Cutting it, boiling it , freezing it
The –OH+ group is most acidic proton in ln-OH as shown in figure (a). The proton is circled in the figure.
The stabilisation of the conjugate base produced is stabilises due to resonance factor. The possible resonance structures are shown in figure (b).
The acidity of a protonated molecule depends upon the stabilisation of the conjugate base produced upon deprotonation. The conjugate base of ln-OH is shown in figure (a).
The possible resonance structures are shown in figure (b). As the number of resonance structures of the conjugate base increases the stabilisation increases. Here the unstable quinoid (unstable) form get benzenoid (highly stable) form due to the resonance which make the conjugate base highly stabilise.
Thus the most acidic proton is assigned in ln-OH and the stability of the conjugate base is explained.

Answer:
True
Explanation:
This is because the Earths ionisphere was distrubed which makes radio communications.
