Answer 1

Answer:

(c) earth worm and rabbit

Answer 2

Answer:

b) only in vertebrates

Explanation:

In all vertebrates (animals having a backbone or spinal column) and a few invertebrates (animals lacking a backbone or spinal column), an iron-containing protein called haemoglobin is responsible for oxygen transport. Hemoglobin is a red pigment and gives the blood a red colour. The cockroach does not have haemoglobin.
