Answer:
Polar bear.
Explanation:
Polar bear is the organism that has the adaptations which enable it to survive in the tundra. the polar bear has white skin and fur on all its body which helps it to camouflage in the ice and to prevent the loss of heat from its body. The polar bear catch its favourite food in the water which is the fish that provide high nutrition to the polar bear. It is a good swimmer and have large paws with small bumps that helps it to provide support while walking on the ice. The scientific name of polar bear is Ursus maritimus whose features are described in the question.
Most likely to be true about a scientific theory: It is accepted by a large scientific community.

am not totally sure but I think the answer is D
Answer:
Despite a substantial literature using life cycle assessment (LCA) approach, the extent to which second and third generation biofuels are more sustainable than the first generation remains a subject of debate. Although the existence of limitations due to LCA variability and uncertainty, this paper intends to determine global tendencies based on a statistic and critical interpretation of previously published study results, reviewing 61 recent papers addressing an environmental evaluation of microalgae biofuels. Such information is compared to the same impact indicators for fossil fuels and for ethanol and biodiesel from terrestrial crops in Europe and Brazil. For each case, the system boundaries and the methodological choices were precisely described. The sustainability potential of all biofuels was evaluated by the Global Warming Potential (GWP), the Energy Ratio (ER) and the Land Use (LU), allowing a broad estimation of the biofuels’ contribution to climate change mitigation, their net energy efficiency and their competiveness with food production chain.
