Lactic acid fermentation differs from ethyl alcohol fermentation in that

a. in ethyl alcohol fermentation co2 is also produced
b. lactic acid fermentation can occur in all living things
c. ethyl alcohol fermentation can only occur in plants
c. only lactic acid fermentation can produce more atp

A. In ethyl alcohol fermentation CO2 is also produced

In ethyl alcohol,  fermentation CO2 is additionally created. The final result of ethyl alcohol fermentation has just 2 carbons, where the finished result of lactic corrosive maturation. Lactic acid maturation is a metabolic procedure by which glucose and other six-carbon sugars are changed over into cell vitality and metabolite lactate. Liquor maturation is a natural procedure which changes over sugars, for example, glucose, fructose, and sucrose into cell delivering ethanol and carbon dioxide as a side-effect

they float because they are less dense than the water itself

something denser than water, like a rock, will sink to the bottom

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
