Textbook Question
Chapter 41, Problem 9TYU
EVOLUTION CONNECTION Lizards and snakes cannot breathe while chewing food because the connection between their external nostrils and their esophagus is in the mouth. In contrast, mammals can continue breathing through the nostrils while chewing food in the mouth. However, choking sometimes occurs when the paths of air and food cross each other. Thinking about the high oxygen demand of active endotherms, explain how the concept of descent with modification explains this "imperfect" anatomy of some amniotes (see Figure 34.2 to review vertebrate phylogeny).

Design an experiment to test whether dropping keys down the back of the neck causes nosebleeds to stop. (Assume parents of all children in the school have given permission for their participation in the experiment and you have followed ethical guidelines for research with human subjects. One possible explanation for why keys down the back might actually be effective in stopping a nosebleed is that they are cold, causing blood vessels to constrict. Treatments should be randomly assigned to the children. Describe how you accomplish this. That is, when a child with a nosebleed comes to the nurse's office, how will you know which treatment he or she should get?arrow_forwardDescribe the respiratory function in amphibians.in some detail pleasearrow_forward

Insect and bird wings are similar in function but not in structure. Paleontologists have used fossils to trace the evolution of the modern camel. Many organisms have structures with no apparent function found during embryo development. The presence of gill slits and tails in early vertebrate embryos shows that they may share a common ancestor.arrow_forward

Reptiles, in contrast, have a single inner ear bone. The lower jaw of reptiles is composed of multiple bones while the lower jaw of mammals is a single bone. Fossil and developmental evidence indicate that the inner ear bones of mammals evolved from lower jawbones. This suggests that the inner ear bones of mammals are Mammal skull, including ear bones eardrum Reptile skull, including ear bone eardrum Oa transitional trait a vestigial structure a living fossil an exaptation an analogy MacBook Air DII DD F2 F3 F4 F5 F6 F7 F8 F9 F10 FV 23 24 % & 3 4. 6 7 8 U D F G H J K ~の * 00 O OOarrow_forward
