The reactants of cellular respirationare oxygen and sugar, which are theproducts of photosynthesis. ... When plants are placed in darkness, cellular respiration continues, using ATP to convert sugar into ADP and releasing carbon dioxide. Photosynthesis stops in the absence of light energy.
(705/224) / (224/224)
224/224 = 1.
So (705/224) / (224/224) = (705/224) / (1/1).
Dividing 2 fractions is equal to multiplying the first fraction by the inverse of the second:
(705/224) / (1/1) = (705/224) * (1/1) = 705/224.
Hope this Helps! :)
C. Genetic variation
Bacteria are very numerous, and random mutation of bacterial DNA generates a wide variety of change, including resistance. It happens through mutation and selection. Not only are they capable of sharing genetic bits of DNA to related and unrealted species they can develop ways to remove the antibiotic before it reaches its intended area via biochemical pumps or enzymes to inactiavte the antibiotic.
