Answer:

8900 CFU/mL

Explanation:

Colony Forming Units (CFU) is a value that indicates the degree of microbiological contamination of an environment. It expresses the relative number of microorganisms of a given taxon in a volume of one cubic meter of water.

UFC is the minimum number of separable cells on the surface, or inside, of a semi-solid agar medium that results in the development of a visible colony of the order of tens of millions of descending cells. The CFUs can be pairs, chains or clusters, as well as individual cells. Colony forming unit.

Calculation

Colonies * Dilution = CFU/mL

89          *  (100/ 1 mL) = CFU/mL

8900 CFU/mL

Write a scientific explanation to describe the impact of the infected papaya trees on the toucan population.
seraphim [82]

The infected papaya trees will produce less carbohydrates or chemical energy for the toucan. If there were fewer carbohydrates within each papaya, the toucan's muscle cells would not be able to obtain as much chemical energy as they normally do. This chemical energy will be converted into mechanical energy or heat flow, which the toucan uses to fly.

Therefore, the lower amount of mechanical energy and heat flow from the muscle contractions, it would result into a reduced amount of kinetic energy of motion when the toucan is flying.
