The difference between the macromolecules consumed by Americans and the elemental composition of human body is that these macromolecules provides energy, support and help speed up reactions in them while the elemental composition of human body are used to build proteins, carbohydrates and nucleic acids to perform their respective functions.
How macromolecules provide support.Macromolecules helps to give structural support to the body system through the proteins in our diet by consumption. They do this by acting either as hormones or carriers to aid metabolic activities.
From the task above, we can see that about 78% of carbon in American bodies are from the consumption of corn. Whereas in France, the percentage of carbon which is found in their body system is not upto 78% but 15%.
It has also been proven practically that the food substances consumed by Americans contains majorly of carbohydrates. Lipids and proteins is in low amounts or quantities, roughly almost the same amount.
Macromolecules such as glucose combines with oxygen to produce water, carbon dioxide and ATP in the reaction below:
C6H12O₂ + 6O₂ + 36 ADP+ 36 Pi → 6CO₂ + 6H₂O + ATP
The pi above means the phosphate group and ADP means adenosine diphosphate.
So therefore, we can deduce that macromolecules are of great importance in the diet system of the Americans as it provides structural support to them.

Which chemical leads to a pleasurable sensation when released in the brain, such as in response to nicotine?.
Answers
Your bloodstream carries nicotine to your adrenal glands, which are located above your kidneys.Your heart rate, respiration, and blood pressure all rise as a result of the glands releasing adrenaline.You experience a lot of positive emotions at once when taking adrenaline.
How does nicotine cause a pleasant feeling?
The body is stimulated by the adrenaline surge, which raises heart rate, blood pressure, and breathing rates.Nicotine stimulates the brain's reward circuits, which control reinforcement and pleasure perception, just like other substances do. The idea that the hunger and mood disorders linked to nicotine withdrawal may be caused by reduced serotoninergic transmission is supported by the fact that nicotine stimulates brain serotonin production while nicotine withdrawal has the opposite effect (4, 5). Cigarettes contain nicotine, a bioactive substance that stimulates the central nervous system's nicotinic acetylcholine receptors (nAChRs) to provide pleasant effects.Nicotine dependency results from the central nervous system's plasticity being altered by repeated nicotine consumptionNicotinic acetylcholine receptors that are found in the brain are where nicotine mostly manifests its effects.It increases Ach release and metabolism by stimulating presynaptic acetylcholine receptors.It also stimulates the dopaminergic system, raising the level of dopamine in the nucleus accumbens as a result. Dopamine, serotonin, norepinephrine, acetylcholine, gamma-aminobutyric acid, and glutamate are just a few of the neurotransmitters that are increased in release when nicotine binds to nicotinic receptors in the brain. Serotonin and dopamine may be released when nicotine is administered acutely (23), but chronic nicotine administration to rats has been demonstrated to reduce serotonin levels and serotonin biosynthesis (24, 25). Dopamine is released into the brain within seconds of inhaling cigarette smoke, vape mist, or chewing tobacco, which makes people feel good.People need to consume more and more cigarettes to achieve the same positive feeling over time as their brain starts to want the effects of Nicotinic receptor agonists include nicotine and ACh.Nicotinic receptors bind to nicotine and ACh, which results in a conformational shift that either opens or closes the receptors' ion channels, altering the functional state of the receptors. Nicotine, which is highly addictive, is a component of both smoking and vaping.It has been established that smoking causes cancer, which can be fatal.However, it has been established that vaping can lead to fatal lung diseases.The truth is that smoking is deadly.To learn more about nicotine refer

Answers
A chain of repeating monomers to make a larger molecule is called a Polymer.
Monomer-based compounds that combine to form polymers.
Large molecules known as polymers are constructed from single, comparable repeating components (monomers).
A polymer is made up of numerous monomers because the prefix poly- signifies "many" or "multi-."
Any of a group of organic or synthetic compounds known as polymers are made up of macromolecules, or very large molecules, which are just multiples of simpler chemical building blocks known as monomers. Numerous natural and man-made materials, as well as a large portion of the components in living things, are composed of polymers.
A polymer is created when many monomers are linked together. Polymers can be compared to a chain of interconnected paperclips in several ways. A polymer is a big molecule consisting of monomers, which are littler molecules bonded together.
Plastic is a subset of polymer since all plastics are polymers but not all polymers are plastic. Plastics are long-chain molecules created by large monomers while polymers are homogenous molecules created by small monomers. Plastics are manmade materials yet polymers can also be natural.

small, nonpolar, hydrophobic molecules such as fatty acids easily pass through a membrane's lipid bilayer. very slowly diffuse through a membrane's lipid bilayer. require transport proteins to pass through a membrane's lipid bilayer. are actively transported across cell membranes.
Answers
Small, nonpolar, hydrophobic molecules such as fatty acids pass readily through a membrane's lipid bilayer.
The cell membrane, which is selectively permeable and controls the passage of molecules into and out of the cell, facilitates the movement of substances or molecules throughout the cell.
A thin polar membrane composed of two layers of lipid molecules is the lipid bilayer. These membranes are flat sheets that surround all cells and act as a continuous barrier.
A lipid-rich cell membrane will not repel small, nonpolar hydrophobic molecules like fatty acids, so they enter the cell through simple diffusion. This indicates that they easily and without assistance penetrate the lipid bilayer of a membrane. Because they are a class of lipids and soluble in the lipid layer of the cell membrane, fatty acids are able to pass through the lipid-bilayered membranes easily.

For the data to be considered reliable the variability of the values should be small. Repeated scientific research increases credibility. Results may change over the course of different studies or under different conditions.
It is therefore important that the experiment itself is reproducible.
