Explanation

A ductile material can undergo significant plastic deformation, meaning it can be stretched or bent without breaking, before fracturing.

This property is known as ductility, and it allows for large strains to occur before the material reaches its breaking point.

Common examples of ductile materials include metals such as copper, aluminum, and steel, as well as certain polymers.

The nucleoid is a central area within the cytoplasm where the single, circular chromosome of the prokaryote resides. 

Explanation

The majority carriers in a p-type semiconductor are holes. 

When a semiconductor material is doped with trivalent impurity atoms (like Boron), it creates "holes" where electrons are missing, effectively giving a positive charge.

These holes then become the majority charge carriers, meaning they are the primary contributors to electrical current flow in the material.
