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. what did engelmann conclude about the congregation of bacteria in the red and blue areas?

Engelmann concluded that aerobic bacteria move to these areas because these areas had the most oxygen being released.

Explanation:

Engelmann's experiment showed that bacteria were moving due to the oxygen generated in the active chloroplasts in the algae.

Another possible outcome of Engelmann's experiment was also the relationship between red and blue light wavelengths and the amount of heat released in Photosynthesis.

explanation:

with the profits from the european sales, merchants purchased europe's manufactured  goods, including tools and weapons. then the merchants shipped those manufactured  goods, along with the  american  sugar and rum, to west africa where they were bartered for  slaves.
