By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth. There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind. This is why scientists cannot be certain about how life began.
        
             
        
        
        
The assumption in this problem is that the gas, CO2, is ideal and that the ideal gas law is applicable such that,
                                     n = PV/RT
We simply substitute the given values to the equation above,
                                 n = (1 atm)(V) / (0.082 Latm/mol.K)(T)
                                           n = 12.20 V/T
        
             
        
        
        
Answer:
Glycolysis is actually a series of ten chemical reactions that requires the input of two ATP molecules. This input is used to generate four new ATP molecules, which means that glycolysis results in a net gain of two ATPs.
