Cosmos Unveiled: From Geocentric Views to Panspermia
1. Geocentric Model: The initial belief was that the Earth was the center of the universe, with the sun, moon, and stars revolving around it.
2. Copernicus and Galileo: Unlike the past, today we know the sun is the center of our solar system. Therefore, they would not be considered crazy for proposing a heliocentric model.
3. Determining Earth’s Age: The age of the Earth is determined by studying organic remains in rocks and fossils, which provide clues about its history over millions of years.
4.

Mendel’s Laws of Inheritance
For his experiments on inheritance, Gregor Mendel chose the common pea plant. His findings laid the foundation for modern genetics.
- Mendel’s First Law (Law of Segregation): When crossing two varieties of plants or animals that differ in one character, all the first-generation hybrids exhibit the dominant character. The recessive character reappears in the second generation.
- Mendel’s Second Law (Law of Independent Assortment): When crossing two varieties of plants that differ
Organ Donation, Transplants, and Stem Cell Therapies
Who Can Be a Donor?
A donor is typically a person in a state of brain death, where brain function has ceased, but the heartbeat is artificially maintained to keep organs viable for transplantation. In some cases, a living person can be a donor, particularly for tissues or renewable organs.
Spanish Legislation Regarding Organ Donation:
- Establishment of brain death by medical professionals.
- Respect for the deceased’s wishes regarding organ donation.
- Diagnosis of death must be made by physicians.

Reproductive Biology: Mutations, Gametes, and Fertilization
Reproductive Biology: Key Concepts
Mutation: An alteration in the genetic information (genotype) of a living being, causing a change in its pattern. This change occurs suddenly and spontaneously and can be inherited by offspring.
Ovules: These are the female sex cells, large, spherical, and motionless. From puberty, an egg matures in one of the ovaries every 28 days and travels through a fallopian tube.
Sperm: The male sexual reproductive cell or gamete, responsible for fertilizing the egg and providing
