Sveta_85 [38]

Answer:

b

Explanation:

The correct answer would be 6.4 x 10^6 cells/ul.

For 1 x 10-6 dilution, the plating factor is 10^6. To find the number of bacteria in the original sample, the plating factor is multiplied by the colony count per ul.

<em>Number of viable bacteria = plating factor x colony count/ul</em>

Since 10 ul gives 64 colonies.  1 ul will give:

         64/10 = 6.4 colonies.

Therefore, the viable bacteria in the original sample = 6.4 x 10^6 cells/ul

The correct option is b.

What is a ecosystem? write 2 to 5 sentences to explain it​
Nonamiya [84]

Ecosystem is that it is a community or group of living organisms that live in and interact with each other in a specific environment.

For instance, tropical forests are ecosystems made up of living beings such as trees, plants, animals, insects and micro-organisms that are in constant interaction between themselves and that are affected by other physical (sun, temperature) or chemical (oxygen or nutrients) components.


An ecosystem consists of a community of organisms together with their physical environment.
Ecosystems can be of different sizes and can be marine, aquatic, or terrestrial. Broad categories of terrestrial ecosystems are called biomes.
In ecosystems, both matter and energy are conserved. Energy flows through the system—usually from light to heat—while matter is recycled.
Ecosystems with higher biodiversity tend to be more stable with greater resistance and resilience in the face of disturbances, or disruptive events.
