Question - In 2015 in Alaska, an enormous number of walrus females and their calves gathered on a single beach. In the past, the walruses would use sea ice as a place to rest and nurse their calves, but due to human activity and global warming, large amounts of the ice have melted. Explain what consequences could happen to the walruses and their ecosystem in this situation over time.
Answer - Since there is so much global warming problems it rises the temperature of earth. Female walruses nurse their calves on ice blocks but since most, or not all have been melted they cant nurse in the future because there not used to a different environment. Eventually over time their species will die out and become extinct.
Your question is rather unclear but from what I can tell either there were not an even amount of Petri dishes or some of them were left open while others were not.
