Answer - Jaw evolution in air and water .It is mainly to increase respiratory efficiency. It is used to pump water across the gills of fish and air to the lungs of amphibian .jaw of tetrapods show varrying degree of mobility used to chew food and predators can predate.
Different pattern of jaw found ind different environment. Based on the function of that vary . In aquatic environment it is used mainly to pump water. In mammals used for speaking and chewing food.
Challenges depend upon various factor including environmental factor and body architecture.

PHYSICAL GEOGRAPHY WILLIAM MARSH Describe an example of an open system and a closed system on Earth. For the open system, describe the specific energy and matter that comes into and/or out of the system. For the closed system, describe why energy and matter stays within the system. Using Figure 2.7 and Figure 2.16 in the textbook as a reference, describe any patterns you see on Earth that can be categorized based on latitude or longitude. In other words, look...
