It’s either the first 2 but I’m leaning towards the first answer
<span>Styrene, or C6H5-CH=CH2, can form even lengthy chains, via free radical polymerization. This involves the breakage of the double bond that allows the addition of another molecule of styrene. Repetition allows the addition of another, and yet another, styrene molecule. The process can be controlled to limit the number of additions.
Another addition polymerization involves carbocations. Double- or triple-bonded compounds interact with acids to form positively charged carbocations. These can combine with additional molecules to form lengthier carbocations capable of further repeating the process.</span>
<span>The correct answer is letter A, disorders in individual genes are responsible for Down's syndrome.
This is a human genetic disorder that is associated with physical growth delays, characteristic facial features, and a mild to moderate intellectual disability. This is a condition in which the genes make a copy of the chromosome 21. </span>
