Answer:
Legionella tends to form biofilms and infect other microbial cells as intracellular pathogens.
Explanation:
The Legionella genus of the bacteria is a group of gram-negative bacteria that can cause legionnaires disease.
The<em> Legionella pneumophila</em> is a species of this genus which can cause legion pneumonia. The bacteria lives in the freshwater and is resistant to chemical treatment like chlorine and the biocide treatment.
The reason for this resistance is since this species form a polysaccharide layer around the colony of the bacteria which is resistant to these treatments and also the bacteria prove parasitic to the protozoans which feed on these bacteria.
Thus, the selected option is the correct answer.
That would be living things.
Because...
Biosphere= living things
Lithosphere= land
Hydrosphere= water
Atmosphere= air
I think it is gravitational force.
The correct answer is - D. use a greenhouse.
If the climate is not suitable for a certain exotic plant, and the reason for that is that it is colder than the place from where the plant originates, than the best solution is to plant it in a greenhouse.
The greenhouse will provide higher temperature for the plant throughout the whole year, so it is will have a proper temperature, similar to the one it is adapted to. Also, it will receive sufficient amounts of light. It will be protected from the outside influences such as the cold winds, snow, low temperatures, so it will have a good chance of growing.
