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>

kykrilka [37]

Answer:

The answer is A.

Explanation:

To test if the selenium from the mine has an effect on the fish living in the lake which i assume is close to the mine, testing the tissue of the fish from that lake and comparing it to the selenium levels of the fish from a nearby lake would be a testable hypothesis because there is a comparable aspect and there should be a difference in the numbers between the fish from the two lakes because of their distance to the mine.

I hope this answer helps.
