What are two examples of proteins

In surgery for a heart attack, a middle-aged woman has a vision of God by her bedside. “Will I die?” she asks.

God says, “No. You have 30 more years to live.”

With 30 years to look forward to, she decides to make the best of it. So since she’s in the hospital, she gets breast implants, liposuction, a tummy tuck, hair transplants, and collagen injections in her lips. She looks great! The day she’s discharged, she exits the hospital with a swagger, crosses the street, and is immediately hit by an ambulance and killed. Up in heaven, she sees God. “You said I had 30 more years to live,” she complains.

“That’s true,” says God.

“So what happened?” she asks.

God shrugs. “I didn’t recognize you"

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.
