Answer
the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.
When growing cultures, the agar is<u> inoculated</u> to separate pathogenic colonies of organisms from colonies of normal flora.
Agar is the medium that is used for growing natural, common flora of microorganisms as the majority of the microorganisms can sustain in the agar medium.
If we want to determine a separate pathogenic colony of organisms in an agar medium then we need to inoculate the agar growth medium so that the pathogenic organism is separated from the normal flora of the microorganism. This technique allows us to filter out the cells that have the pathogenic microorganism in it.

Answer:
Bacteria provides vitamins to humans
Explanation:
The correct answer would be that bacteria provides vitamins to humans.
<u>By definition, mutualism is a type of symbiotic relationship between two organisms in which both benefit from each other.</u>
Bacteria in the gut of humans that provides vitamins to humans also benefit by making the human gut their shelter. While the vitamins represent an important nutrient to humans for their proper functioning, the shelter is also necessary for the bacteria for their safety.
<em>Hence, the observation that bacteria provide vitamins to humans is consistent with the argument of researchers that some bacteria found in the human gut are in a mutually beneficial relationship with humans.</em>
Answer:
How can you determine experimentally whether a bacterium is a psychrophile or a mesophile? incubate two cultures, one around 10°C and the other around 35°C. If it grows in the lower temperature incubator, it is a psychrophile. If it grows in the higher temperature incubator, it is a mesophile.
