A change in dna (deoxyribonucleic acid) in an organism that results in a new trait is known as a mutation. A mutation usually takes many generations to be visible, it is passed through the next generation and they inherit the same DNA and they might be a small change in that same DNA and then that genetic information is passed to the next generation and so on, after being passed and altered for a long time the results will be visible.

<h3>
What is Respiration?</h3>
- The respiratory system, also known as the respiration or ventilatory system, is a biological system in both plants and animals that consists of a variety of organs and structures that are employed for gas exchange.
- Depending on the organism's size, environment, and evolutionary background, the anatomy and physiology that cause respiration vary widely.
- In land animals, the respiratory surface is internalized as the lining of the lungs.
- Gas exchange in the lungs takes place in millions of tiny air sacs, known as alveoli in mammals and reptiles and atria in birds.
- The air is in close touch with the blood in these tiny air sacs because they have an abundant blood supply.
