List the strengths and the weaknesses of the model used in this task

In the world of science, models can be described as representations of phenomenons which are present on the Earth or in the universe. A model can be an idea, mathematical calculation, equations, visual representation or computational representation etc.

The strength of a model is that it helps to understand the phenomenons of nature easily. It helps us to understand concepts which otherwise would have been very difficult to understand.

The drawback of a model is that if it is wrong, then people will get the wrong idea of a concept.

If you mess up one of the moon phases then you won't get a arcuate drawing.  

You learn how the moon works and how it reflects off the sun.  

You also can see how the phases differ month to month.

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.
