Please it’s worth 40 points I promise I will follow you and mark brainleist. Explain how a mouse uses its senses to act when it is in danger. Describe how the mouse heart and lungs work together when it smells a predator. Explain how the model can show what happens to the mouths breathing when it smells a predator this is a test please help

When the twitching pink nose of a mouse detects danger, the animal has to act fast. Fortunately, a predator rapidly triggers the release of stress hormones in the mouse and prompts behaviors that reduce the risk of it becoming the predator’s latest snack.  helping explain how the brain translates danger signals detected by the nose into a physiological response. The research offers clues to the larger puzzle of how animals, including humans, perceive and respond to fear.

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.
