Glycolysis rearranges a 6-carbon glucose molecule into two 3-carbon molecules of

The answer is pyruvate.

Explanation:

Glycolysis is a metabolic pathway of carbohydrates that deals with the break down of glucose to pyruvate by a series of enzyme catalyzed biochemical steps.

   During glycolysis the intermediate di hydroacetone phosphate(1 molecule) undergo isomerization to form form 2 molecules of glyceraldehyde-3-phosphate.

 From there rest of the intermediates of glycolysis are produced with 2 molecules and as a result the end product of the glycolysis is 2 molecules of pyruvate.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
