The centre of the nucleus is an atom
Answer:
The agent causing the pneumonia, where bluish-green pus was found, is most likely Pseudomonas aeruginosa.
Explanation:
Pseudomona aeuriginosa is a gram-negative bacteria that is one of the main causes of hospital-acquired infections, including pneumonias in mechanically ventilated patients.
One of the characteristics of P. aeuriginosa is the formation of a bluish-green pus, since it has the capacity to form cyanide-based blue pigment upon contact with the organic tissues it infects. This is the reason why previously P. aeruginosa was called a pyocyanic bacillus.
<em> The other options are not correct because the only bacterium that produces blue-green pus is P. aeruginosa.</em>
The correct answer to this question is option"blue-green".
Reason:
The carotenoid is a yellow-orange pigment that absorbs blue light which gives plants there green color.
Therefore the answer should be option B.
Hope this helps!!!
