Why is carbon said to provide a "backbone" in many molecules? (1 point) 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 have 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-carbon bonds are unusually strong, so carbon can shape a steady, strong backbone for a huge atom. Since a C particle can frame covalent bonds to upwards of four different molecules, it's appropriate to shape the essential skeleton, or "spine," of a macromolecule.

Explanation:

For one thing, carbon-carbon bonds are unusually strong, so carbon can form a stable, sturdy backbone for a large molecule. ... Because a C atom can form covalent bonds to as many as four other atoms, it's well suited to form the basic skeleton, or “backbone,” of a macromolecule.
