Maslow’s Hierarchy of Needs
Maslow’s physiological needs are the basic human needs that depend on satisfaction for survival. (The most important statement is that they are innate, unlearned, and intuitive.)
- Security: These needs serve as extra consolidation obtained from the moment of safety, so that the individual feels safe and protected.
- Social: These needs are related to the individual’s emotional development and the need for social association.
- Esteem: These needs affect the individual’s self-confidence.
Mendel’s Laws and Genetics: Understanding Heredity
Mendel’s Laws and Genetics
Introduction
In the second half of the nineteenth century, Gregor Mendel discovered the basic principles governing the transmission of hereditary characters. For his experiments, he chose the pea plant due to its easy cultivation, rapid growth, and easily observable characteristics. Pea plants can self-pollinate and are easy to artificially impregnate, making them ideal for study. Mendel selected seven characteristics and utilized pure lines, studying the descent along several

Hazard Classification
Based on the origin, hazards are classified into:
Biological Hazards
Processes or phenomena of organic origin or conveyed by biological vectors, including pathogenic microorganisms, toxins, and bioactive substances. Examples of biological hazards include:
- Epidemic and pandemic diseases
- Plant or animal contagion
- Insect or other animal plagues and infestations
Geological Hazards
Geological processes or phenomena that may cause loss of life, injury or other health impacts, property damage,

Rocks
The lithosphere has various types of rocks. Rocks are naturally occurring, hard, consolidated, inorganic materials composed of one or a large number of minerals.
Types of Rocks
- Igneous: These rocks are formed by the solidification of magma in the Earth’s interior or lava on the surface. Igneous rocks are composed of primary minerals, which are predominantly silicates. Igneous rocks sometimes overlap with sedimentary and metamorphic rocks.
- Sedimentary: Sedimentary rocks are formed by precipitation
