1) What are the universal themes of Star Wars? Give 3 examples. The universal themes of Star Wars are relationship to machines‚ issues of friendship and obligation to other people around you‚ and control over your destiny. Darth Vader is an example of relationships to machines because he is more machine than man‚ as an antagonist in Star Wars. Star Wars also has an infinite amount of examples on the issues of friendships and people around you‚ with character relationships playing out. The case of

concentration of total protein in human serum‚ a total protein assay was performed by using the Biuret reagent. Proteins react to this compound because it contains two amide bonds. When the Biuret reagents is introduced to a sample of protein‚ it forms a blue or violet complex. The concentration of albumin in human serum is determined by using the Bromocresol green (BCG) reagent. When albumin and the BCG reagent are combined‚ the solution turns into a blue-green complex. Albumin and globulin are protein components

but his actual son. This boy’s name is Lucas. B1) What is the theme of the story? The theme of the story is quite complexed as it both deals with the racism issues which unfolded in the incredebly segregated society of South Africa‚ and at the same time shows how complicated and paradoxical this separation of black and white people is.

a framework for evaluating different chemistries‚ and an ideal to strive for in new reaction chemistry (1‚2‚3). Green Chemistry Principle: Atom Economy Atom economy means maximizing the incorporation of material from the starting materials or reagents into the final product. It is essentially pollution prevention at the molecular level. For example‚ a chemist practicing atom economy would choose to synthesize a needed product by putting together basic building blocks‚ rather than by breaking down
