SFS2. Students will use various scientific techniques to analyze physical and trace evidence.. . b. Analyze the morphology and types of hair.. The word “gel” lends itself to confusion ­because it originally described the nail product’s physical state, but over the years it has become a generic name of the product category. Whereas liquid-and-powder nails are a two-part system in which the powder has already been polymerized to its full ­extent, gel is a homogenous product in which the monomers and oligomers (strings of monomers) stay in a semi-liquid/semi-solid state because it hasn’t polymerized. Think of gel as premixed acrylic.. Larva:. Whole body,. Lateral Habitus.. The larva is. a. pproximately . 6 mm in length.. Mouth. Red imported fire ant, . Solenopsis. . invicta. .
