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 without passing light through a prism, what would you predict?A) There would be no difference in results.B) The bacteria would be relatively evenly distributed along the algal filaments.C) The number of bacteria present would decrease due to an increase in the carbon dioxide concentration.D) The number of bacteria present would increase due to an increase in the carbon dioxide concentration.E) The number of bacteria would decrease due to a decrease in the temperature of the water.

Answer:

The correct answer will be option-B

Explanation:

Theodor Engelmann performed the experiment to study the relationship between the production of oxygen in response to the wavelength of light. This was observed by the congregation of the bacteria in the red and blue wavelength.

In the given condition, if no light is passed through prism then the bacteria will not be accumulated in a particular area instead will be evenly distributed as the algae will produce the oxygen evenly and the concentration is not high in any particular area.

Thus, Option-B is the correct answer.

Svet_ta [14]

Answer:

The human population is yet to reach its carrying capacity. However, the following will suggest that humans have reached their carrying capacity.

1. When humans are unable to increase food production which is expected to sustain a larger population.

2. When humans' use of resources, in general, is greater than resource availability.
