We inhale air that is comprised of roughly 78 percent nitrogen and 21 percent oxygen, as well as a trace amount of other gases.
When we exhale, the components are the same, they just come out in different amounts. Exhaled air is made up of about 78 percent nitrogen, 18 percent oxygen, and four percent carbon dioxide, excluding those trace gases.
TL;DR
Inhaled: 78% Nitrogen, 21% Oxygen, 1% Other Gases
Exhaled: 78% Nitrogen, 18% Oxygen 4% Carbon Dioxide
It compares the number of mutations that exist in the DNA of two different species.

The nucleus is enclosed by a double layered cellular membrane called the nuclear membrane.
<h2>Nucleoplasm</h2>
The nucleus contains a nuclear sap, enclosed by the nuclear envelope, which is known as the nucleoplasm. This holds the nucleoli and suspends the chromatins.
<h2>Nucleolus</h2>
The nucleolus is a sub-organelle present inside the nucleus. It can be observed as a dark spot under the microscope.
Nucleoli are made up of proteins, ribosomal RNA (rRNA), and ribosomal DNA (rDNA).
<h2>Chromatin network</h2>
DNA gets associated with protein molecules to form chromatins.
Chromatins are present in the nucleoplasm.
The four systems that describe the functions of the circulatory systems are:
- oxygen is delivered to cells throughout the body by this system
- This system removes carbon dioxide from organs & delivers it to the lungs.
- Carbon dioxide exits the body through this systems
- This system's organs pass oxygen into the bloodstream.

What is the circulatory system?
The circulatory system can be referred to as a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of humans or other vertebrates.
The circulatory system includes the cardiovascular system, also known as the vascular system which consists of the heart and blood vessels.

Arteries
Explanation:
Arteries have a higher amount of elastin than veins. Thus, veins have a higher ratio of collagen to elastin thsn do arteries
