Answer:

The transport of proteins and other bioactive materials from endoplasmic reticulum to the nucleus without the involvement of transport vesicles is the main beneficial for the cell to be continuous with the nuclear envelop.

Explanation:

The rough endoplasmic reticulum or RER that contain ribosomes on its surface is directly continuous with membrane of nucleus.

     This helps nucleus to gain access to the proteins and other materials generated within endoplasmic reticulum.

   If endoplasmic reticulum faces biological problems such as unfolded protein accumulation in the ER is hazardous to the cell.During such circumstances ER send specific signal to the nucleus.

  The nucleus respond to that signal by reducing the rate of protein synthesis,so that the ER would get some extra time to fold the required proteins essential for cellular functioning,

sleet_krkn [62]

Answer:

P. aeruginosa

Explanation:

<em>P. aeruginosa</em> is a gram-negative bacteria that belongs to the family Pseudomonadaceae.

From the given question the following points lead us to conclude that the colony that will be growing would be of P. aeruginosa :

1. Flat spreading colonies with a metallic sheen on SBA - <em>P. aeruginosa</em> is known to produce smooth colonies with flat edges.

2. Fluorescent green color in the media with clear colonies on cetrimide agar - <em>P. aeruginosa</em> is known to produce pyoverdin which is a fluorescent pigment under low iron conditions.

3. Medium clear colonies that have a "fruity or grape-like odor" on MacConkey Agar - <em>P. aeruginosa</em> has a sweet fruity odor which is its characteristic odor because of the production of trimethylamine.

Thus, from all these characteristics one can conclude that the organism in the culture is <em>P. aeruginosa. </em>
