polyester

B
polystyrene

C
polyurea

D
polyamide
Question 2
1 / -0

Fat soluble vitamins are stored in

A
Adipose and liver

B
Stomach

C
Eyes

D
Pancreas

Solution

Vitamins which are soluble in fat and oils but insoluble in water are fat soluble vitamins. These are vitamins A, D, E and K. They are stored in liver and adipose (fat storing) tissues.
Question 3
1 / -0

Which of the following statements regarding cellulose is not true?

A
Its main natural source is cotton.

B
It is insoluble in water, but soluble in ammoniacal copper hydroxide solution.

C
The molecular weight of cellulose varies between 20,000 and 50,000.

D
Cellulose is a branched chain polymer.
Question 4
1 / -0

For macromolecules to form, one or more of the following criteria are essential

A
The repeating structural units are derived from some simple and reactive molecules

B
The simple molecules are linked to each other by covalent bonds

C
These are made by joining of repeating structural units on a large scale

D
All of these

Solution

Macromolecule is made by joining repeating structural units (monomers) on a large scale by covalent bond formation between the simple and reactive molecules
Question 5
1 / -0

Macromolecules are one of the following

A
Ethers

B
Esters

C
Amines

D
Polymers

Solution

Polymers are higher molecular weight macromolecules. These are formed by joining of repeating structural units on a large scale.
