The correct answer is "limited prey is driving the bears to seek food in human settlements".
Due to the warming of the Arctic waters, the ice is melting, resulting in a serious decline of floating winter ice.

That is why polar bears are driven to human settlements to look for food.

So the answer in this question would be that the RNA for that gene is not translated into protein.
The nucleus is labeled M.
