Neolithic Revolution and the Rise of Civilizations
The Neolithic Revolution
The disappearance of ice fauna in many places forced the steppe, which was adapted to the cold, to migrate to other regions. Humans began to enclose animals for their milk and meat, and thus arose the first livestock species. The domesticated species were the ox, horse, sheep, goat, and dog. Both humans were interested in the cultivation of plants. Women, who were in charge of recollection, noticed that when seeds fell to the earth, plants grew. Thus, agriculture arose. The

The Plasma Membrane
The plasma membrane is a biological membrane that separates the interior of a cell from the extracellular environment. It allows interactions and is selective.
Composition
- Lipids: These are amphipathic molecules. The main ones are phospholipids (which have hydrophobic tails and polar heads), cholesterol (found only in animals, interspersed between phospholipids), and glycolipids (occurring in the outer monolayer; in plants, they appear more often).
- Proteins: These fulfill the biological
Philosophical Perspectives on Society and Human Nature
Plato (427-347 BCE)
Plato believed that human need is the origin of society. Man needs many things, and his capacity for action is limited, so he needs society. The individual depends on the state. The virtue and happiness of the individual depend on the virtue and happiness of the state. The polis will only be just if a relationship based on duty exists between the different social classes that constitute it.

The Human Factor in Relationships
Social life defines how humans live and interact within social groups. These groups relate to other groups and municipalities, forming provinces and even nations. Life, to which man is subordinated by his natural features, requires him to act as a member of a social group and not as an isolated individual. His actions are aligned with others. The human factor is of radical importance in relationships, imposing rules to establish a basic order. Without this order,

Mendel’s Laws and Genetic Mutations: Inheritance Principles
Mendel’s First Law: Law of Uniformity
Mendel’s first law, the law of uniformity, concerns the first filial generation. The offspring resulting from crossing two pure strains (homozygous) forms a group of hybrids that have uniformity, both in terms of genotype and phenotype. This law is based on the crossing of two varieties homozygous for a character (homozygous dominant and homozygous recessive, AA and aa), which gives rise to a uniform F1 generation (Aa), with the same phenotype as the dominant
