Which of the following polymers is found in stockings and ropes?

polystyrene

polypeptide

polysaccharide

nylon

Option D, Nylon

Explanation:

Polystyrene is made up of polymerization of styrene. It is brittle, stiff and transparent and is widely used in making containers, disposable utensils etc. Thus it is not the correct answer

Polysaccharides are biomolecules made up of polymers of sugars and constitute structural components of cellulose. Thus it is not the correct answer

Polypeptides are chains of amino acids which are biomolecules and thus cannot be the right choice of answer

Nylon, are synthetic polymers which have high melting point and are resistant to abrasion. Thus they are used in ropes and stockings

Hence the correct answer is nylon

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
