Place the objects in order from least greatest mass to greatest mass terrestrial gas giant ice dwarf ice giant

Correct order from least greatest mass to greatest mass:

The above given list contains the names of different planets depending upon their compositional characteristics. According to this list gas giants are heavier and then ice dwarfs and then ice giants.

Terrestrial which means planet earth is top on the list, which is lighter in weight than other planets.

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.

explanation:

the darker peppered moth species were favored due to the fact that the industrial revolution had made all the nearby trees a darker color instead of white.
