How does having an amniotic egg affect the lifestyle of reptiles?
What is "the amniotic egg allows eggs to be laid and develop on land, so reptiles can have a completely terrestrial life"

What is ossification of cartilage to bone, autodigestion of tail to make legs, change from gills to lung, vascularization of skin, change from 2 to 3 chambered heart.
500
Name 4 ways reptiles have adapted to life on land.
What is amniotic eggs, stronger skeleton, scales and waterproof skin to reduce water loss in dry land air, claws, some have 4-chambered heart for more efficient circulation for movement.

Describe the difference between single loop circulation and double loop circulation. What do we call the 2 loops in double loop circulation?
Single loop: Blood from heart to gills to body. Double loop: Blood from heart to lungs and back = pulmonary circuit, blood from heart to body and back = systemic circuit.
