Answer:
Greatly affect.
Explanation:
This modification to the sampling procedure greatly affect the results because timing of sampling is very important that can change the results of an experiment. The water quality of lake is different in different times of the day due to human activities.

Answer:
Biological populations of same species become isolated due to geographic changes such as mountain building or emigration.
Explanation:
Answer:
By changing pyruvate into lactic acid with this transfer of electrons.
Explanation:
Transfer of electrons helps the lactic acid fermentation process repeat itself because the pyruvate molecule takes electron from NADH which is reduced to lactic acid so indirectly with the transfer of electrons helps the lactic acid fermentation process to repeat itself. If these electrons are not transferred from NADH to pyruvate molecules so the lactic acid is not formed.
