Use the following information to answer the questions below.Theodor W. Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of algae to different wavelengths of light. He added aerobic bacteria and then noted in which areas the bacteria congregated. He noted that the largest groups were found in the areas illuminated by the red and blue light.If you ran the same experiment as Engelmann without passing light through a prism, what would you predict?

Welder has some fixed costs that vary depending on the level of production.  The fixed costs of the existing facility is $1,000 per month.  When production is high, Welder can rent the facility next door for $500 per month.  At either facility, the variable cost is $1 per unit. The sales price is $5 per unit. The result is that Welder has these cost structures over these ranges: 1: from 1-300 units the cost structure is, $1,000 + $1 per unit 2.: from 301-500 units the cost structure is, $1,500 + $1 per unit When does Welder have zero profits?
