Biology
I. Fundamentals of Biology
I.1. Basic concepts of biology
An organism is a hierarchy of complex systems. By organizing simple systems in the body, new, previously inaccessible, opportunities appear. With each new level, unpredictable opportunities appear.I.2. Biological systematics
Reviewing the accumulated knowledge about living organisms, it becomes possible to identify special features in each living organismII. Fundamentals of Biochemistry
In living organisms, for the most part, there are four types of organic molecules: carbohydrates, lipids (fats), proteins (proteins) and nucleic acids. The main composition is carbon, hydrogen and oxygen, proteins also contain nitrogen and sulfur, nucleic acids and lipids contain nitrogen and phosphorus.
II.1. Carbohydrates
Carbohydrates, or sugars, are the main carriers of energy. Other macromolecules also consist of sugarsII.2. Lipids
Known as fat. They store energy and protect us from the cold. Tightly packed sugar in the bodyII.3. Proteins
Proteins are the most common element in the body, form tissues, and also regulate many processes in our organzymeII.4. Nucleic acids
Keepers and distributors of genetic information are the calling card of a living organism, the basis of our existence is DNAIII. Cell Biology
Cytology is a branch of biology that studies living cells, their organelles, their structure, functioning, processes of cellular reproduction, aging and death.
