text III end text. Four-chambered hearts

Select an Answer

text I end text only

Correct Answer: 
Yes

text III end text only

Correct Answer: 
No

text I end text and text II end text only

Correct Answer: 
No

text I end text and text III end text only

Correct Answer: 
No

text I end text, text II end text, and text III end text

Correct Answer: 
No

This type of question requires you to look at the choices text I end text, text II end text, and text III end text, and decide which combination of characteristics belongs to birds and does not belong to mammals. The correct answer is feathers only, (A). Clearly, most mammals give birth to live young, so text II end text is not part of the correct answer. This rules out choices (C) and (E). Four chambered hearts are also characteristic of mammals (humans, for instance) so choice text III end text is not part of the correct answer. This rules out choices (B) and (D).
