GarryVolchara [31]

Answer:

The correct answer will be option-C

Explanation:

The plant absorbs the sunlight to perform photosynthesis which helps produce the sugar molecule used by the plants.

The plants absorb maximum sunlight at two wavelengths that are red and blue wavelength by chlorophyll and other pigments. The efficiency of photosynthesis is also measured maximum at these two active wavelengths called action spectrum.

In the given question, since the efficiency of photosynthesis has been discussed which could be measured with the production of oxygen and consumption of carbon dioxide. The experiment performed by the Engelmann showed that aerobic bacteria got concentrated in the blue and red wavelengths as the output of the photosynthesis were observed maximum.

Thus, the selected option is the correct answer.

a student viewing a cell with a microscope observes a cell wall, a cell membrane, and a nucleus.the presence of these structures

vekshin1

My answer may not be precise, but I believe if you changed your question to "The presence of these structures indicates that the student is looking at a cell of what organism", then I would safely say a plant, because plants, unlike animals, have cell walls in addition to cell membranes. :) Hope this helps!
