- Xna0114-runtime polymorphism
With runtime polymorphism, the selection of a method for execution is based on the actual type of the object whose reference is stored in a reference variable, and not on the type of the reference variable on which the method is called.

Preface
This module is one in a collection of modules designed primarily for
teaching
GAME 1343 Game and Simulation Programming I at
Austin Community College in Austin, TX. These modules are intended tosupplement and not to replace the textbook.
An earlier module titled
Getting Started
provided
information on how to get started programming with Microsoft's XNA Game Studio.
Object-oriented programs exhibit three main characteristics:
- Encapsulation
- Inheritance
- Polymorphism
I have explained encapsulation, inheritance, and compile-time polymorphism in
earlier modules. I will continue my explanation of polymorphism in this modulewith an explanation of runtime polymorphism using method overriding and class
inheritance. I will defer an explanation of polymorphism using interfaceinheritance until a future module.
Viewing tip
I recommend that you open another copy of this module in a separate
browser window and use the following links to easily find and view the Listings while you are reading about them.

What is polymorphism?
As you learned in an earlier module, the meaning of the word polymorphism is something like
one name, many forms .
How does C# implement polymorphism?
Also as you learned in an earlier module, polymorphism manifests itself in C# in the form of multiple methods having
the same name.

How bacteria create energy to survive?
Bacteria doesn't produce energy they are dependent upon their substrate in case of lack of nutrients they are able to make spores which helps them to sustain in harsh environments

explain assimilatory nitrate reduction
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
