The rapid growth of the human population during the last two centuries is indirectly responsible for which environmental concern, that in turn, will lead to future species extinction is decreased biodiversity. The correct answer C.
The correct answer is: decrease motility in the intestine, dilate bronchioles in lungs, dilate pupils, secrete epinephrine, and speed up heartbeat.
Being chased by a coyote constitutes a highly stressful and threatening situation for the rabbit. This means that the rabbit's physiology will adapt and the body will get prepared for action, that is to run and avoid the coyote.
This response is called an acute stress response (also called fight or flight response) and includes a hormonal cascade. The autonomic nervous system is responsible for the regulation of this response.
All of the changes in the sympathetic nervous system are an effort to boost the body with the necessary energy to run as fast as possible. Some of these adaptations include the dilation the lungs' bronchioles and the speeding up of the heartbeat, in order to accelerate the lung and heart action. Also, the motility of the intestine is decreased to a point where digestion nearly stops, in order for the blood flow to support the muscular action. Finally, one part of the adrenal glands triggers the secretion catecholamines, meaning the norepinephrine and epinephrine hormones.

Answer:
variation means that some individuals have traits better suited to the environment than others. so in natural selection everyone's adaptions and traits are different and variated. not everyone is gonna have the best adaptation, that would make everyone op.
make sure to answer it in your own words lol, if you copy and paste itll
link your teacher to this answer
