Hematoxlyin and Eosin - 1. Hematoxylin = basic dye stains acidic molecules like nucleus, DNA, RNA 2. Eosin = acidic dye stains basic molecules like cytoplasm Plasma membrane - lipid bilayer in which proteins are embedded -has 2 layers 1. hydrophilic = head 2. hydrophobic = tail 2 types of proteins in plasma membrane: 1. Integral membrane proteins = inside the plasma membrane 2. Peripheral membrane proteins = outside of the membrane

Soft Water/ Rain water - Best for shampooing and allows shampoo to lather freely Hard Water - Minerals that lessen the ability of the shampoo to lather Purified water/Deionized water - Main ingredient in shampoo Surfactant - has two ends the HYDROPHILIC HEAD and LIPOPHILIC TAIL Hydrophilic Head - Attracted to water Lipophilic Tail - Attracted to dirts and oils Acid Balanced Shampoo - pH of 4.5-5.5 Jheri Redding - first to introduce pH balanced shampoo...
