Now it is clear that genes are what carry our traits through generations and that genes are made of deoxyribonucleic acid (DNA). But genes themselves don't do the actual work. Rather, they serve as instruction books for making functional molecules such as ribonucleic acid (RNA) and proteins, which perform the chemical reactions in our bodies.Proteins do many other things, too. They provide the body's main building materials, forming the cell's architecture and structural components. But one thing proteins can't do is make copies of themselves. When a cell needs more proteins, it uses the manufacturing instructions coded in DNA.The DNA code of a gene—the sequence of its individual DNA building blocks, labeled A (adenine), T (thymine), C (cytosine) and G (guanine) and collectively called nucleotides— spells out the exact order of a protein's building blocks, amino acids.
Occasionally, there is a kind of typographical error in a gene's DNA sequence. This mistake— which can be a change, gap or duplication—is called a mutation.
Social convoy
Social convoy refers to a group
of people who accompanies an individual on the journey of life. A social convoy
provides personal, familial, cultural, and even professional supports for an
individual. Family members usually comprise a part of social convoy and its
makeup changes over time.

Explanation:
The breathing process is the process of breathing in, also called inhalation and breathing out, also called exhalation. Inhalation and exhalation are important processes for a smooth respiratory experience.
Air (containing oxygen) from our external environment enter our body system via our MOUTH or NOSE. The air then passes from the PHARYNX into the LARYNX or voice box, which connects into the TRACHEA or wind pipe, which conveys the air into the lungs via its branched tubes called BRONCHI. These pipes that air passes through in order to reach the lungs are generally called AIR WAYS.
Inhalation (breathing in) involves the taking in of air into the LUNGS (main organ of respiration). It occurs when the diaphragm (muscle separating the thorax from abdomen) contracts and moves downward towards the abdomen. This allows the lungs to expand, allowing air to enter into the lungs via the NOSE or MOUTH down the TRACHEA or windpipe.
As soon as air reaches the lungs, the air passes through the bronchi (tubular branches of the trachea) into the ALVEOLI or air sacs. The delivery of oxygen in the inhaled air is carried out in the CAPILLARIES (a blood vessel that carries blood) that surrounds the alveoli. This alveoli conveys oxygen from the lungs into the bloodstream and carbon dioxide out of the bloodstream into the lungs (a process called GAS EXCHANGE).
Breathing out or exhalation of the carbon dioxide in the lungs (waste product of respiration) occurs when the diaphragm relaxes and moves upward, causing the lungs to deflate as the carbon dioxide is released through the trachea into the mouth or nose where it leaves the body system.
