Answer:
a) and b) All the 12 plates taken by the food controller for the analysis are test plates in light of the fact that the food inspector is trying distinctive spinach from 10 unique bundles and do try different things with every one of the 12 plates.
C) and D).only #11 plate is a negative control since he utilized the spinach which isn't cleaned. so microorganisms can develop on that pate because they have the positive condition to develop themselves.
e) and f). all #1 - #10 and #12 plates are positive control plates since he swipes all the plates and spinach that can be the reason for the development of microbes so there is an excess of fewer opportunities to the defiling of spinach and he is playing it safe.
Answer:
<u>Attributes of E. coli articulation frameworks </u>
Advantages:
-
Quick articulation
-
Simplicity of culture
-
Significant returns
-
Cheap
-
Genome alterations conceivable
-
Large scale manufacturing quick and practical
Disadvantages:

<u>Animal Cells:</u>
Advantage:
- nearness of post interpretation adjustment
Disadvatages
Issues with creature utilization
Can get sullied with creature diseases
Exorbitant downstream preparing
Primary succession occurs in areas without life, while secondary succession occurs in places that were previously inhabitated.
Hope this helps!
