Contrast the different types of lungs of vertebrates. Amphibians Lizards Mammals
Answer and explain both please. Use this evolutionary tree representing the relationships among a group of vertebrates to answer questions 17 and 18. According to evolutionary theory, the letters at each branch point indicate the common ancestor for groups beyond that point. - Lung fishes Amphibians Mammals Lizards and snakes . Crocodiles - Birds 17. Which was the last (most recent) common ancestor of crocodiles and lizards/snakes? 18. Which of the following can be concluded from this evolutionary tree? A....

Describe the heart of different animals in circulation and explain. Fish 2 chambered Heart. Amphibians 3 chambered heart. Birds and Mammals. Thank you!
Characterize the following groups of chordates/vertebrates: Chondrichthyes, Actinopterygii, Amphibians, Reptilia (include birds), and Mammalia (include monotremes, marsupials, and eutherians). Include information about their unique structural features, reproduction cycle, and nutritional acquisition.

Question 5 1 pts Lungs in mammals compared to lungs in spiders would be considered a(n) analogous trait homologous trait synapomorphy autapomorphy Question 6 1 pts Given that some volume of air remains in the respiratory tract of mammals (residual volume) how would the partial pressure of O2 (PO) in the alveoli compare to the atmospheric PO2?! It would be lower than in the atmosphere It would be higher than in the atmosphere It would be equal to the atmosphere

Most fish and amphibians do not provide parental care, but most birds and mammals do. What is the pattern between amount of pounds of caregiving, and egg size/number? Why do you think this pattern exists?
