Answer:
Answer below
Explanation:
Well when natural selection occurs, genes that don't benefit the speicies, or more accurately, harm it by ruining camoflague. Natural selection can result in one creature evolving into 3 different species when those creatures get put into different environments that promote genetic mutations that help them survive. After a long while of genetic mutations coming and going to adapt to their environment, those three members of the species are no longer the same species because they've all adapted to different environments.
Answer:
In the mentioned scenario, norepinephrine and acetylcholine are the neurotransmitters, which would have been present at the higher concentrations in Sean's brain.

It also gets released in the bloodstream as a hormone, where it augments the rate of heart and causes the blood vessels to contract. Another neurotransmitter called acetylcholine signifies the chemical that is released by the motor neurons to instigate the muscles.
Answer:
Intermediate neuron
Explanation:
Interneurons are the "middle man", neither a sensory or motor nueron, that creates neurial circuits, connecting a broad class of neurons in the spinal cord and brain. They enable communication from motor and sensory neurons in the central nervous systems and are classified into two groups; relay and local interneurons. Through neurial circuits, the brain is able to manage and deal with complex stuff such as decision-making and learning.
A. They had different types of food. This resulted in many different breeds of finches.
In animals, the circulatory system performs a similar function because it transports vital nutrients around the body of the animal, just like how xylem and phloem transport water, minerals, and sugar to different parts of the plant.
