Question 41

Why dissecct a frog

Answer 41

mamals/ and anfibeans are related 300 million years ago

Question 42

how are frogs and humans and mamals similar

Answer 42

both have circulatory system & digestive system

Question 43

How are frogs and humans different

Answer 43

ciculatory system is a frog simpler, frog heart has 3 chamers, humans have 4. Frog exchange gases through skin and lungs.
