Why is carbon said to provide a “backbone” in many molecules?(1 point)ResponsesCarbon atoms have half-full shells of electrons, allowing electrical signals to pass through them easily.Carbon atoms have half-full shells of electrons, allowing electrical signals to pass through them easily.Carbon atoms have full shells of electrons, allowing electrical signals to pass through them easily.Carbon atoms have full shells of electrons, allowing electrical signals to pass through them easily.Carbon atoms have long narrow shapes, allowing many other atoms to attach to them.Carbon atoms have long narrow shapes, allowing many other atoms to attach to them.Carbon atoms can form chains and branches with each other, and other atoms can attach to these.

Carbon atoms can form chains and branches with each other, and other atoms can attach to these.

Carbon atoms can form chains and branches with each other, and other atoms can attach to these.

The correct response is:

Carbon atoms can form chains and branches with each other, and other atoms can attach to these.

Carbon atoms have the unique ability to form strong covalent bonds with other carbon atoms, creating long chains or branches. This ability allows for the formation of complex organic molecules, as carbon atoms can act as a "backbone" by providing a stable structure upon which other atoms can be attached. This characteristic is what makes carbon so versatile in forming the basis of many biological molecules.
