How can biomass energy use improve water quality? A) The combustion of biomass material to produce energy improves water quality by filtering out
pollutants.
B) Biomass energy use does not require water, which reduces the impact of other energy
producing technologies on water quality,
C) Biomass energy is less costly when used to purify water.
D) Soil erosion and sedimentation are decreased during biomass crop growth.
E) All of the above

D) Soil erosion and sedimentation are decreased during biomass crop growth.

Explanation: edge

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.

but there is no

i guess you forgot putting it.
