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.
Answer:
The correct answer will be option-B.
Explanation:
Cellular respiration is a slow process which produces energy from the oxidation of food components which could be glucose, fatty acids and proteins.
The process proceeds in four steps: glycolysis, link reaction, Krebs cycle and electron transport chain.
The energy molecules are produced when a high energy electron gets reduced and the released energy is stored in the form of energy molecules which could be ATP or energy equivalents like NADH and FADH₂.
These reducing equivalents donate its electrons during electron transport chain where the electrons flow to the last electron acceptor called oxygen.
Thus, Option-B is the correct answer.
It is because of high specific heat capacity of water
Answer:
Because melting can be reversed ( freezing )
