Question

2.2 Fill in the Table: Animal Number of Heart Chambers (e.g., 3) Separate Pulmonary System? (yes or no) Perch Frog Pig Pigeon 2.3 Drawing: Diagram the three (2, 3 & 4 chambers) systems of the fish, frog and pig showing in outline: the gill or pulmonary systems, the systemic systems and the heart structures. Indicate the structures for gas exchange. 2 Chambers 3 Chambers 4 Chambers

Answer 1

2.Answer:

animal	chambers	do it have separate pulmonary system
perch	2	NO,they breath with the help of gills
frog	3	yes
pig	4	yes
pigeon	4	yes
