Translation: List at least 5 objects that were formerly made from another material and are now made from a polymer. Identify what polymer it is
Answer:
Five object now replaced with polymers
1) automobile body parts. (polypropylene, polyurethane and PVC)
2)TV cabinets. (polystyrene polymer)
3) composites for golf clubs. (carbon fibre reinforced polymer CFRP)
4) fibers for clothing and carpet. (acrylic and nylon)
5) foams for coffee cups (polystyrene)
Answer:
Quaternary structure
Explanation:
Hello!
A protein can be characterized by:
Primary structure: it is the linear sequence of amino acids.
Secondary structure: The amino acid sequence is folded by intermolecular interactions.
Tertiary structure: A greater folding of amino acids is observed by intermolecular interactions and disulfide bridges.
Quaternary structure: Two or more chains of folded amino acids join to form a new, more complex structure.
Successes with your homework!
Answer:
The correct answer is electrons.
Explanation:
The electrons refer to the negatively charged constituents, which are arranged in the orbits around the nucleus of an atom. It determines all the chemical and physical characteristics of an atom except the radioactivity and mass. It is a stable subatomic particle witnessed in all the atoms and functioning as the chief carrier of electricity in solids.
<span>The pressure inside a coke bottle is really high. This helps keep the soda carbonated. That is, the additional pressure at the surface of the liquid inside the bottle forces the bubbles to stay dissolved within the soda. </span><span>When the coke is opened, there is suddenly a great pressure differential. The initial loud hiss that is heard is this pressure differential equalizing itself. All of the additional pressure found within the bottle pushes gas out of the bottle until the pressure inside the bottle is the same as the pressure outside the bottle. </span><span>However, once this occurs, the pressure inside the bottle is much lower and the gas bubbles that had previously been dissolved into the soda have nothing holding them in the liquid anymore so they start rising out of the liquid. As they reach the surface, they pop and force small explosions of soda. These explosions are the source of the popping and hissing that continues while the soda is opened to the outside air. Of course, after a while, the soda will become "flat" when the only gas left dissolved in the liquid will be the gas that is held back by the relatively weak atmospheric pressure.</span>
