Which type of interaction stabilizes the alpha (α) helix and the beta (β) pleated sheet structures of proteins?

D) Hydrogen bonds

satellites are frequently used to make observations of the orbit on earth

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
