The comparison between DNA molecules of different species has revealed the degree of similarity of their genes, which shows the evolutionary relationship. The same is true for proteins that ultimately reflect genetic similarities and differences. Cytochrome c is a protein present in all living beings that do aerobic respiration, consisting of 104 chained amino acids.
In this tissue the intracellular substance is reduced, and the lipid-rich cells are called adipose cells. It occurs mainly under the skin, performing functions of energy reserve, protection against mechanical shocks and thermal insulation. It also occurs around some organs such as the kidneys and the heart.
Disposable items are already laundered when they arrive at cooperatives. Disposable cup production comes to consume 500 ml of water. In times of water scarcity, the need to revise water-saving habits has become a priority. Washing garbage before recycling is one that needs to be reviewed.
"In nature nothing is created, nothing is lost, everything is transformed" Does the above sentence sound familiar? Because it has to do with chemistry and was said by the French chemist Antoine Laurent de Lavoisier.

It is a blood clotting disorder that lacks factor VIII, one of the proteins involved in the process, found in the plasma of normal people. Haemophiliacs have a tendency to have severe bleeding after minor injuries, such as minor injury or tooth extraction.
The water molecule is made up of two hydrogen atoms and one oxygen. Already the nitrogen gas, which exists in the atmosphere, is formed by the union of two nitrogen atoms. The same goes for oxygen gas. We then say that oxygen is a simple substance, since it is formed by the union of chemically equal atoms.
