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:

Give the symbols for the element that makes up each of the following:
______Carbohydrates.______ Lipids. _____DNA. _____Proteins.
Answers
Answer:
The correct answer is :
1. CHO
2. CHO
3. CHONP
4. CHON
Explanation:
Carbohydrates are composed of the carbon, hydrogen, oxygen in the ration of 1:2:1 which means hydrogen atoms are double than oxygen and carbon atoms. Carbohydrates are also known as sugars or polymer of sugars.
Lipids are composed of long chains of fatty acids made up of carbon, hydrogen, and oxygen molecules that are insoluble however ade up of organic molecules.
DNA or deoxyribose nucleic acid is the basic unit of cell and known as genetic material. It is made up of ribose sugar, a nitrogenous base, and phosphate backbone so elements that make these nutrients are Carbon, hydrogen, and oxygen with nitrogen and phosphorus.
Proteins are made up of amino acids that have carbon, hydrogen, oxygen, and nitrogen element in them.
The 4 macromolecules are namely Carbohydrates, Proteins, Nucleic acids, and Lipids. The composition of each macromolecule is defined by the elements present.
The symbols for the element that makes up each macromolecule are listed below:
Carbohydrates-H, C, and O(Hydrogen, Carbon, and Oxygen) Lipids-H, C, and O(Hydrogen, Carbon, and Oxygen) DNA-O, H, N, C, and P(Oxygen, Hydrogen, Nitrogen, Carbon, and Phosphorus) Proteins-O, H, C, and N(Oxygen, Hydrogen, Carbon, and Nitrogen)Thus, the symbols of the element that make up Carbohydrates, Proteins, Nucleic acids, and Lipids are defined.

Based on this information, what conclusion can the scientist draw regarding this nucleic acid?
Answers
Answer:
Based on the information , the scientist concluded that the regarding nucleic acid is DNA (Deoxyribonucleic Acid) .The structure of DNA is attached below -:
Explanation:
PROPERTIES OF DNA -
In humans and almost all other species, DNA, or deoxyribonucleic acid, is an inherited substance. Almost every cell in the body of an individual has the same DNA. The DNA information is stored as a code consisting of four chemical bases: adenine (A), cytosine ( C), guanine ( G) and thymine ( T). In order to form units called base pairs, DNA bases pair up with each other, A with T and C with G. A sugar molecule and a phosphate molecule are both affixed to each base. Together, a nucleotide is called a base, sugar , and phosphate. Two long strands are arranged with nucleotides that form a spiral called a double helix. The double helix structure is much like a ladder, with the base pairs forming the rungs of the ladder and the molecules of sugar and phosphate forming the vertical sidepieces of the ladder.An significant DNA property is that it can duplicate itself or create copies of it. In the double helix, each strand of DNA will serve as a template for duplicating the sequence of bases. As each new cell requires to have an exact copy of the DNA present in the old cell, this is important as cells divide.Hence, the structure identified and conclude by the scientist is DNA (deoxyribonucleic acid). Thus, the structure of DNA is attached below.

4. Root cells of plants take in some minerals from the surrounding soil by spending
energy. After the plant obtains enough minerals to maintain health, the plant will
continue to absorb minerals from the soil. Which reason best explains why root cells
need to spend energy in order to transport some minerals into cells?
Answers
Answer:
i know its 3
Explanation:
yes buddy
After the plant obtains enough minerals to maintain health, the plant will continue to absorb minerals from the soil.
This is because Mineral concentration is higher in root cells than in the surrounding soil. Thus option D is correct.
What are the effects of minerals do plants growth ?
For a better growth plants need minerals, can be absorbed through the roots by active transport in the form of mineral ions.
Minerals have a major role in electron transport, enzyme activation, development, maintenance of structural components etc.
The two most essential minerals are magnesium ions and nitrate ions needed for proper growth of plants.
Beside this various fertilizer are used like Nitrogen fertilizers which increase the growth as well as high yield of the crops.
Excess use of mineral cause mineral toxicity, for example eutrophication happens when excess nitrate enters into aquatic system causes the death of aquatic animals.
