Answer:
By panting or breathing heavily.
Explanation:
<em>An ectothermic animal is one whose body temperature depends on the temperature of the external environment.</em>
The body of ectotherms regulates temperature depending on the temperature of the external environment where such animal finds itself.
Hence, when the temperature of the external environment rises as a result of hot air, the body of an ectotherm (that is homeothermic, that is, maintain a relatively constant body temperature irrespective of the temperature of the external environment) will adjust so as to keep its temperature relatively constant.
Dogs generally pant (breathe heavily) to bring their body temperature back to normal whenever it rises beyond normal due to rigorous physical activities or high external temperature.
<em>Hence, a fox will most likely pant in response to hot air temperature just like dogs.</em>

An eye contains receptors called photoreceptors viz rod and cone cells. Cones are cone-shaped structures and are necessary for daylight vision. Unlike cones, rods are rod-like structures and are necessary for dim-light vision. Rods are far more numerous than cone cells.
Answer:
A. fertilizer runoff from farms, animal manure, and stormwater runoff.
Explanation:
Agriculture and Urbanization are the main factors responsible for the “dead zone” in the waters of the Chesapeake Bay.
In the eastern part of the Chesapeake Bay, you have agricultural activities such as the poultry farms which produce huge amounts of manure that are later washed through runoff into the bay. Also, nitrogen from the use of fertilizers in the farmlands are being washed along into the bay leading to increased level of nitrogen in the waters which reduces the availability of oxygen in the bay. The level of oxygen in the bay is reduced as the excess nutrients that are washed into the bay causes an overgrowth of algae, which later sinks and decompose in the water.
There are many factories located by the western part of the bay where there is also the concentration of urban centers. Much nitrogen is released into the air, which later ends up in the bay.
As a result of urbanization, large volume of water is created in the form of stormwater runoff, as rain falls on driveways, rooftops, roads and other pavement, making difficult for the water to be absorbed into the ground. This large volume of water moves quickly into the bay. Many pollutants such as nitrogen, bacteria, pesticides, trash etc, are washed along into the bay.
