• C. b-iv
• D. d-iv

Answer 1

Answer: (A), (B), (D)

The correct options are
A a-i
B b-ii
D d-iv

• Erythrocytes or red blood corpuscles contain haemoglobin. It binds with oxygen to form oxyhaemoglobin. In the tissues which are deficient in oxygen, oxyhaemoglobin liberates oxygen.
• Adipose tissue consists of several adipocytes or adipose cells. They contain fat globules. Adipose tissue is found below the skin and between internal organs. It prevents heat loss from the body.
• Platelets are cell fragments. They help in the clotting of blood at the time of injury.
• Monocytes are phagocytic in nature. They engulf bacteria and cellular debris.
