Which of the following are true about hydrogen bonds?
a hydrogen bond is stronger than a covalent bond
they are the strongest bonds that form between molecules
the attraction between the hydrogen atom of one water molecule and the
oxygen on another water molecule is an example
a hydrogen bond is stronger than an ionic bond

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

sorry, but you do not have posted the diagram.
