Q1(a) List the three(3)major phala (Division) of the kingdom plantae
The three major divisions of the kingdom Plantae are:

Q2(b) briefly explain the major events that happens in the stomach
The stomach primarily functions in both mechanical and chemical digestion. Food is churned by muscular contractions, mixing it with gastric juice. Gastric juice contains hydrochloric acid (HCl), which denatures proteins and kills bacteria, and pepsin, an enzyme that begins the breakdown of proteins into smaller peptides. This process transforms food into a semi-liquid mixture called chyme.
