Understanding the Scientific Method The scientific method has the following steps:
1. Ask a question
2. Research
3. Form a hypothesis
4. Design and Perform the experiment
5. Analyze the results
6. Draw a conclusion
Sheryl's Mom works third shift so she sleeps during the day. Sheryl and her
friends like to listen to loud music after school but they don't want to disturb
Sheryl's Mom. Put the step number next to each step of the scientific method
for this problem.
doutrido her Mom's room and measure the sound.
How do I put them in order?

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.
