Hello,
The answer is to "prove your hypothesis".
Reason:
Researchers do experiments to prove there hypothesis they will most likely do the experiment a few times in older to have the conclusion valid therefore proving his or her experiment.
If you need anymore help feel free to ask me!
Hope this helps!

Answer:
Is that an actual question for school?
The tundra is one of the coldest biomes so I would say that the animals have to be adapted. Maybe fur coats♀️they have to be warm and they also need food..I dunno I would think about how they live within the biome—(I added a picture of a tundra Biome)
The troposphere contains 80% of the the atmosphere, including the majority of gases and water vapor.
Hope it helps!
