Answer:
Sympathetic division is responsible for the nervousness, pounding in the chest and the butterfly movement in the stomach while parasympathetic division overest a and digest the nervousness.
Explanation:
The nervousness experienced when someone is about to speak in front of a class is caused by the sympathetic system which have divergent effects as many different effector organs are activated together for that same purpose. I.e More oxygen are inhaled and delivered to skeletal muscle. The respiratory, cardiovascular, and musculoskeletal systems are all activated at the same time causing an unstable reaction to the central nervous system...
On the other hand, the parasymthetic division causes the central nervous system to rest and digest at a very slow rate..
At a point in time the central nervous system triggered an Homeostasis action which posses a balance between the two divisions.I.e symthetic and parasymthetic and then brings about a balance to the body reaction at that same point.
The correct statement is this one: Molecules move from areas of high concentration to areas of low concentration.
This is true also for diffusion outside of organisms, for example diffusion of gases in a room.
The other options are false.

Answer:
Hereditario se refiere al proceso por el cual las características se transmiten genéticamente de padres a hijos.
Explicación:
Hereditario se refiere al proceso por el cual las características se transmiten genéticamente de padres a hijos. La cromatina consta de ADN y proteína que se replica antes de la división celular para formar duplicados de ADN que se distribuyen equitativamente entre las células hijas. Las cromátidas se refieren a las dos mitades idénticas de un cromosoma duplicado replicado y el centrómero es la secuencia de ADN de un cromosoma que une dos cromátidas hermanas entre sí y cada cromátida tiene cuatro brazos.
