Apartial meadow food web is shown. based on this food web, which organisms are direct sources of energy for secondary consumers? a) aphid bird rabbit b) ladybug fox dragonfly c) frog butterfly berries d) mouse snake hawk

Explanation:

Organisms need to detect and respond to changes in their internal and external environment. ... Cells called receptors , which detect stimuli (changes in the environment). The coordination centre, such as the brain, spinal cord or pancreas, which receives and processes information from receptors around the body.of they ouf thomHow does the body respond to changes in its environment

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
