I believe it is 'white fur' because living in the Tundra means it is snowing. Snow is white, so basically, the white fur is specifically for the Tundra.
I hope it helps.
Because, photoautotrophs serves as their carbon sources.
Chemoheterotrophic bacteria are those bacteria that are incapable of producing their own food, they depend on photoautotrophs, which are capable of making their own food by trapping energy from the sun. Thus, photoautotrophs serves as source of food for the chemoheterotrophic bacteria.
The answer to your question would be B) Ground water will increase, and here is why: Since the snow piled up on top on the mountain, when Spring comes around, naturally temperature will rise. Once this happens, the snow will melt and run-off of the mountain. Then, since there is so much water, there will be a large amount of ground water, probably more than normal. I hope this helped you a bit!
<span>All living organisms have a shared ancestor deep in the past, so all living organisms are related to some degree. We might share 99.8% DNA with chimps, but we also share maybe (just a guess, I don't remember the exact number) 24% DNA with lettuce. If all living organisms are related, than their genetic code is universal - one and the same for all organisms.</span>
