Explore the nature of compounds in chemistry, focusing on potassium chloride (KCl) and its dissociation. Understand the distinctions between salts, acids, bases, and buffers. Dive into the characteristic behaviors of each to identify the true nature of KCl.

This video traces the evolution of genetic understanding, beginning with Mendel's foundational pea plant experiments, which birthed basic inheritance laws. It delves into complexities like co-dominance, incomplete dominance, and polygenic inheritance. Highlighting the integral role of DNA, it explains its structure and replication, shedding light on mutations. The narrative underscores the interplay of genes with the environment, introducing epigenetics and the myriad ways genes express, shaping
