Compare and contrast bodily reactions driven by two parts of the ANS: the sympathetic nervous system and the parasympathetic nervous system. Provide examples where each system would be highly active.

Answers

Difference

The sympathetic nervous system prepares the body for the “fight or flight” response during any potential danger. On the other hand, the parasympathetic nervous system inhibits the body from overworking and restores the body to a calm and composed state.

Examples of parasympathetic responses

An easy acronym to remember how and where the PSNS works is SLUDD. This stands for:

Salivation: As part of its rest-and-digest function, the PSNS stimulates production of saliva, which contains enzymes to help your food digest.

Lacrimation: Lacrimation is a fancy word for making tears. Tears keep your eyes lubricated, preserving their delicate tissues.

Urination: The PSNS contracts the bladder, which squeezes it so urine can come out.

Digestion: The PSNS stimulates the release of saliva to promote digestion. It also enacts peristalsis, or the movement of the stomach and intestines, to digest food as well as release bile for the body to digest fats.

Defecation: The PSNS constricts the sphincters in the intestine and moves digested food material down the digestive tract so a person can have a bowel movement.

Examples of the Sympathetic Nervous System Response

The classic case of SNS response is a physical danger, especially with a potential predator, and the preparation of the body for either fight-or-flight. The overall system is designed to enhance voluntary muscle activity while shutting down all non-essential functions.

Arterioles and veins in most vascular beds constrict, reducing blood flow to the skin and digestive organs. Sphincters in the digestive organs also constrict, to control the flow of food from one organ to the next. However, coronary blood vessels, pulmonary circulation and parts of the respiratory tree respond with dilation, to enhance cardiac output. The heart beats with greater contractile force and at a higher frequency as well. Vasoconstriction in many parts of the body also increases blood pressure.

Similarity

Both are the part of ANS. Both originate from the spinal cord. Both have huge influence on physiological process of the body such as respiration, circulation, digestion, urination and reproduction.

The SYMPATHETIC nervous system drives fight-or-flight responses, whereas the PARASYMPATHETIC nervous system drives “rest and digest” responses.

The autonomic nervous system (ANS) comprises the sympathetic system and parasympathetic system.

The sympathetic nervous stimulates 'fight or flight' responses, whereas the parasympathetic system activates 'rest and digest' responses.

The sympathetic nervous system is involved in body reactions such as the acceleration of the heart, constriction of the blood vessels, etc.

The sympathetic nervous system is involved in body reactions such as lowering the heart rate, lowering the flow of blood to skeletal muscles, etc.

Some examples that activate the parasympathetic system include:

Get a massageMeditationSlow breathing

Some examples that activate the sympathetic system include:

StressOverstimulation

In conclusion, the SYMPATHETIC nervous system drives fight-or-flight responses, whereas the PARASYMPATHETIC nervous system drives “rest and digest” responses.

species of bird to the forest. This new species has the same diet as the existing species. Which description predicts what will most likely result from these two species of bird living in the same
ecosystem?
Both bird species cannot occupy the same niche and therefore, one species will die of

Which phrase best describes translation?
A. converts mRNA into a polypeptide
B. catalyzes bonds between amino acids
c.produces RNA from DNA molecules
D. recycles tRNA molecules for reuse

Answers

Answer:

converts mRNA into a polypeptide

The phrase that best describes the process of translation is that it converts mRNA into a polypeptide. The correct option is A.

What is protein translation process?

Translation is the process of converting an mRNA script into a protein. Ribosomes and tRNA are used in this process.

A ribosome decodes messenger RNA (which is produced by transcription from DNA) to produce a specific amino acid chain, or polypeptide, during translation.

The process by which a cell produces proteins using genetic information carried in messenger RNA (mRNA).

mRNA is created by replicating DNA, and the information it contains instructs the cell on how to link amino acids together to form proteins.

Decoding a messenger RNA (mRNA) into amino acids is the process of translation. Polypeptides are made up of amino acids that have been linked together.

The translation process is divided into three stages: initiation, elongation, and completion.

Thus, the correct option is A.

Answer:

NaCl

Explanation:

ionic bond is the bond results from the electro static force of attraction between oppositely charged ions in other words its the linkage formed by the transfer of one or more electron from one atom to another atom

Na gives it electron to chlroine so Na becomes positively charged and Cl becomes negatively charged and they attract each other to form ionic bond

Na is positive Cl is negative

It was built of bright yellow shining stone, with long flights of marble steps, one of which reached quite down to the sea. Splendid gilded cupolas rose over the roof, and between the pillars that surrounded the whole building stood life-like statues of marble. Through the clear crystal of the lofty windows could be seennoble rooms, with costly silk curtains and hangings of tapestry; while the walls were covered with beautiful paintings which were a pleasure to look at. In the center of the largest saloon a fountain threw its sparkling jets high up into the glass cupola of the ceiling, through which the sun shone down upon the water and upon the beautiful plants growing round the basin of the fountain. Now that she knew where he lived, she spent many an evening and many a night on the water near the palace. She would swim much nearer the shore than any of the others ventured to do; indeed once she went quite up the narrow channel under the marble balcony, which threw a broad shadow on the water. Here she would sit and watch the young prince, who thought himself quite alone in the bright moonlight. She saw him many times of an evening sailing in a pleasant boat, with music playing and flags waving. She peeped out from among the green rushes, and if the wind caught her long silvery-white veil, those who saw it believed it to be a swan, spreading out its wings.Based on details in the story, the reader can conclude that the little mermaid A) cares more about humans than her sisters do B) loves the beauty of the princes palace more than her home C) is unhappy with her life below the sea D) is too shy to try and talk to the prince Plz help dont know which one.
