The correct answer will be- all options are correct.
Explanation:
Azotobacter is a genus or a group of bacteria which are involved in the process of nitrogen fixation.
The bacteria can be easily identified by their rod-shaped form and gram staining. Gram staining results show that they are gram-negative bacteria as they stain pink in color due to the thin peptidoglycan layer.
They require oxygen to perform cellular respiration so are called obligate aerobes. Also, they can fix the atmospheric nitrogen by converting it into ammonia.
Thus, all the options are correct.
Answer:
The Visible Light Spectrum and the differences in wavelength and appearance.
Explanation:
I stated this by using the concept of the visible light spectrum. As indicated already in reference to the statements provided, you are observing what is known as the visible light spectrum. This is indicated because the visible light spectrum obtains all the colors of the rainbow and not only that but the statements even use key terms such as wavelengths and different color components. Therefore, signifying that you are looking at the visible light spectrum and observing it on an appearance based observation based on background facts and scientific knowledge. To further evaluate the visible light spectrum in terms of wavelength, both statements A and D provide information regarding the differentiation within wavelengths based on the color in which one perceives. Whereas B and C simply state scientific facts about how the rainbow appears.
