Asolid substance turns into a liquid. which best describes this change? a substance that has a specific volume changes to a substance that has a specific shape. a substance that has a specific volume changes to a substance that has a different volume. a substance that has a specific shape and volume changes to a substance that has a specific volume. a substance that has a specific volume changes to a substance that has a specific shape and volume.

The correct answer is this: A SUBSTANCE THAT HAS A SPECIFIC SHAPE AND VOLUME CHANGES TO A SUBSTANCE THAT HAS A SPECIFIC VOLUME.

Melting occurs when a solid substance turns into a liquid. Solid substances generally have specific shapes and volume. Liquids on the other hand has specific volume but not specific shape; they usually take the shape of the containers in which they are put.

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.
