Explanation:Azotobacter and Rhizobium are nitrogen-fixing bacteria that convert atmospheric nitrogen into forms that plants can use. This process is essential for soil fertility and plant growth.

Explanation:In bacterial photosynthesis, NADH (NAD : 2 H) functions as a reductant, providing the necessary electrons to reduce carbon dioxide (CO_) into organic compounds. This process is part of the photosynthetic electron transport chain in bacteria.

Explanation:The Gram stain is a differential staining technique that classifies bacteria into Gram-positive and Gram-negative based on the structure of their cell walls. This method helps in identifying and categorizing bacteria for diagnostic and research purposes.

Explanation:Members of the genus Bacillus are known for their ability to form endospores. These spores allow the bacteria to survive in harsh environmental conditions.

Explanation:The bacterial cell wall is primarily composed of peptidoglycan, which includes polysaccharides and proteins. Some bacteria also have additional layers containing lipids, making all of these components relevant to the structure of bacterial cell walls.

Explanation:Most bacteria are heterotrophic, meaning they obtain their nutrients by consuming organic matter. Some bacteria are photoautotrophic or chemoautotrophic, but these are less common.

Explanation:Mycoplasma lack a cell wall and a true nucleus. They have a simple cellular structure with ribosomes for protein synthesis but do not have the complex organelles found in eukaryotic cells.

Explanation:Cholera, Tetanus, and Tuberculosis are all bacterial diseases. Cholera is caused by Vibrio cholerae, Tetanus by Clostridium tetani, and Tuberculosis by Mycobacterium tuberculosis.

Explanation:In photosynthetic green sulfur bacteria, hydrogen sulfide (H_S) serves as the hydrogen donor. These bacteria use H_S instead of water to provide electrons for the reduction of carbon dioxide during photosynthesis.

Explanation:Archaebacteria, or archaea, lack murein or peptidoglycan in their cell walls, which is a characteristic component of bacterial cell walls. Instead, they have unique cell wall structures that differ from those of true bacteria.
