A linked list is a data structure consisting of nodes where each node contains a data field and a reference to the next node.
Consists of nodes connected by pointers/references
Does not have a fixed size like an array
Can easily insert or delete elements without shifting other elements

Bubble Sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements, and swaps them if they are in the wrong order.

Polymorphism allows objects of different classes to be treated as objects of a common superclass.
There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).
Example: Inheritance in object-oriented programming languages like Java allows for polymorphism.

Genetically modified organisms (GMOs) are organisms whose genetic material has been altered in a way that does not occur naturally.
GMOs are created by inserting genes from one organism into another to give it a desired trait.
