goblinko [34]2 years ago

If you do not control the variable in an experiment, you cannot have a reliable result. For instance if you are performing an experiment on how a certain plant grows with soda vs water, you cant put one plant in the fridge and one outside in the sun, as you do not know whether or not the different temperatures are affected your results. The variables are not controlled so you cannot know if the results are accurate.

sveta [45]

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>
