Explanation:
Nuclear fusion is a process in which two small nuclei combine together to result in the formation of a larger nuclei.
In Sun, the first step of hydrogen fusion includes combining of two hydrogen nuclei to result in the formation of a deuterium, positron and neutrino.
The nuclear fusion reaction inside the sun is as follows.
Thus, we can conclude that products of step 1 of the hydrogen fusion process in the Sun are isotope of hydrogen, a neutrino, and a positron.
The dilution factor in order to end up with 96 colonies of bacteria is 0.23 × .
For calculating the colony forming unit bacteria;
Colony-forming unit (CFU or cfu) is a measurement of live bacterial or fungi cells and is used to calculate the colony-forming unit of bacteria. CFU counts only viable cells as opposed to direct microscopic counts, which count all cells, both living and dead, using a hemocytometer. Colony-forming units per milliliter (CFU/mL) for liquids and colony-forming units per gram (CFU/g) for solids are used to indicate the results for convenience. The miles and Misra method can be used to compute CFU, which is helpful for assessing the microbiological load and severity of illness in blood and other samples.
∴ cfu/ml = (no. of colonies x dilution factor) / volume of culture plate
23 x cells per mL = 96 × dilution factor
Dilution factor = 23 × / 96
Dilution factor = 0.23 ×
Therefore, the dilution factor in order to end up with 96 colonies of bacteria is 0.23 × .
