Gregor Mendel conducted experiments with pea plants to study inheritance of traits. He found that traits are inherited in discrete units (genes) and that some traits (dominant) mask the expression of others (recessive). Through his laws of segregation and independent assortment, he showed that genes separate and assort independently during gamete formation. This allows for prediction of phenotypic ratios in offspring using a Punnett square. Mendel's work formed the foundation of classical genetics and heredity.
1. The document describes several chemical reactions through equations. It introduces reactants and products for reactions such as HCl + NaOH yielding NaCl + H2O.
2. Tables show data for the reaction of Mg and HCl over time, indicating the reaction is exothermic as heat is produced.
3. Different types of chemical reactions are defined such as exothermic, endothermic, and catalytic reactions which speed up reaction rates.

Sci access 14th : Biology review part 1Tanchanok Pps
The document provides an outline for a biology review course presented by Supanat Phuangphong. The course is divided into three parts that cover microscopes, cells, membrane transportation, cell division, biomolecules, and genetics. Part one focuses on microscopes, cells, membrane transportation, and cell division. Part two covers animal physiology topics. Part three is about botany and genetics. The document then provides more detailed information about various topics from the course outline such as the different types of microscopes, cell structures, and biomolecules.
