Matter that electrons cannot move through easily is?

materials that allow electrons to move through them easily.

insulatorsMaterials through which electrons connot move easily.

elelctric currentThe steady flow of electrons through a conductor.

circuitAn unbroken path through which a electric current can flow.

Explanation:

Materials that have high resistance to electric current are called electric insulators. Examples include most nonmetallic solids, such as wood, rubber, and plastic. Their atoms hold onto their electrons tightly, so electric current cannot flow freely through them.

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.
