Answer:
A homopolymer is a polymer where every monomer unit (mer) of the chain is the same. Polyvinylchloride (PVC) is a homopolymer consisting of vinyl chloride units. Polypropylene consists of repeating propylene units. In contrast, DNA is a polymer that is not a homopolymer. Different sequences of base pairs are used to encode genetic information.

Answer:
144 cm²
Solution:
In this question, the main concept we will be using is that of the area of a square.
\sf{Area\:of\:a\:square=a^2}Areaofasquare=a
2
Area of square P = 36 cm²
We know that the area of a square is a².
∴ a² = 36²
So, a = √36
a = 6 cm
It is given that when we double the side of square P, we get one side of square Q.
So, when we double the side of Square P, we have the equation:
6 x 2 = 12 cm
Hence the side of Square Q is 12 cm.
Area of a square = a²
Area of square Q = 12²
= 12 x 12
= 144 cm²
Hence the correct answer is Option D: 144 cm².

Sometimes, we are confused when we hear to double a number. For example, if we are asked to double 8, multiply 8 with 2.
8 x 2 = 16
So, in order to double a number, simply multiply it with 2.
In the same way, to triple a number, multiply with 3 and to quadruple a number, multiply it with 4 and so on.
