What is the concentration of a suspension that grew 89 colonies on a plate with a dilution of 1:100?
mafiozo [28]

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

Which one of the following hormones stimulates stem elongation and pollen tube growth? A. auxin (IAA. B. ethylene C. gibberellin
Lubov Fominskaja [6]

Hormones stimulates stem elongation and pollen tube growth gibberellins.

A type of plant and fungus hormone is gibberellin. Although its function in the development of fungi is not fully understood, extensive research has been done on it in plants. The other four major groups of plant hormones are auxins, cytokinins, ethylene, and abscisic acid. Gibberellin is one of these hormones. Gibberellin can make seeds come out of dormancy, lengthen cells, promote division, and even play hormonal and signaling roles in the fruiting and senescence processes. Numerous areas of the plant produce different types of gibberellin molecules. There are currently more than 100 distinct gibberellin molecules.
