Marie is experiencing the: Sympathomimetic effects (fight-or-flight state).
The sympathetic nervous system is a component of the autonomic nervous system, managing the activity of visceral organs and the automatic functions of the body, such as breathing or beating of the heart.

* It also has a bronchodilator effect, that is to say, it causes the increase of the diameter of the bronchi.
Answer: One way of creating a variation in a population is through genetic replication errors. This will make a new type of alleles. Environmental factors cause variation such as affecting enzyme activity and function. The changes would show in the phenotype of an organism.
