Answer:
The correct answer is option c. the sympathetic and parasympathetic nervous systems.
Explanation:
The parasympathetic nervous system is the one that controls involuntary functions and acts. It also causes or maintains a body state of rest or relaxation after an effort or to perform important functions such as digestion.
The sympathetic nervous system is the one that controls visceral reactions and reflexes, that is, it controls how our body responds to a threatening situation, as is the case in the example.
Both systems make up the autonomic nervous system which is in charge of controlling the involuntary functions of our body.
Given what we know, we can confirm that the equation to model the situation can be created by multiplying the mass of the astronaut by the force of gravity on earth.
<h3>What is Mass and the force of gravity?</h3>
- Mass is the amount of matter in an object or body.
- What we refer to as weight, is really the force being applied by an object together with the force of gravity.
- Gravity is an invisible force applied by the earth on all objects.
- Together will mass, these forces create what we know as weight.
Therefore, we can confirm that the equation to model the situation can be created by multiplying the mass of the astronaut by the force of gravity on earth, which would be 7.2 kg of mass multiplied by 9.807 m/s² which will result in a "weight" of 156.6 pounds or 71 kg.

The correct answer is hydroxyl, isopropyl and a methyl groups. And menthol is a tri- substituted cyclohexane btw.
hope this helps if my answer is wrong let me know.
Answer:
RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription.
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.
