If each whole number change on the ph scale indicates a tenfold (10x) change in acidity,
with lower numbers being more acidic, how much more acidic is water with a
ph of 2 than water with a ph of 6? just put the number.

Answer: 10000 times

In chemistry, the pH scale is defined as a logarithmic scale used to specify the acidity or basicity of a solution.

In your example, there are four differences in the pH level between the two different water types. As each level indicates a tenfold change, then the resulting value will be 10000 from where .

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.
