Answer=
61] what do mammals have for respiration that reptiles dont
B] Abdominal diaphragm
explaination- all other organs like as rib expansion ,lungs and buccal pump are present in both mammals & reptiles.
but abdominal diaphragm is only present in mammals .in case of reptiles only abdominal diaphragm like structure is present.

62] The chamber of the heart has higher pressure is
B] Left ventricle
explaination- the left ventricle pumps blood to the aorta ,where blood travels to other areas of the body.The left ventricle endures the high pressure ,because it must pump blood to everywhere else in the body.

63]Red blood cells are most analogous to
A]A server in the restaurant
