Wires used in the cables of household gadgets have a plastic covering. this is because plastics a) absorb heat well. b) can be bent to any shape. c) are poor conductors of electricity d) are cheaper than other cover materials.

C) are poor conductors of electricity.

Explanation:

It is important to distinsguish between two types of materials in electricity. First, we have conductors. Conductors are materials that have little opposition to electrical flow. The cables of household gadgets are conductors. On the other hand, we have insulators. The plastic that covers these wires is an insulator. The purpose of it is to stop the flow of current. As plastic is a poor conductor of electricity, it protects people from electrical shock.

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.
