Which TWO descriptions of plants explain how they contributed to the carbon cycle?
denpristay [2]

Plants stored carbon in their tissues to use as energy and plants took in carbon dioxide and released oxygen through photosynthesis. Thus, the correct option is A and D.

<h3>What is carbon cycle?</h3>

The carbon cycle is the ongoing process through which carbon atoms move back and forth between the atmosphere and the Earth. The amount of carbon in this system does not fluctuate because our planet and its atmosphere are a closed environment. The location of the carbon, whether it is on Earth or in the atmosphere, is continually changing.

Plants use photosynthesis to transport carbon from the atmosphere into the biosphere and move it up the food chain. They make sugar molecules by chemically combining carbon dioxide with oxygen and hydrogen from water using solar energy.

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
