Problem: Given the question: Rob is a biologist who is interested in native species conservation. To that end, he conducted two studies, case A and case B. In case A, a non native apex predator C was introduced in formerly apex predator D's habitat. In case B, same non native apex predator C was removed from formerly apex predator D's habitat. He now needs to analyze the results of these studies. In which case predator D's prey selection would be less diversified, case A or case B?
++++++++++++++++++++++++++++++++
The answer is:
case A

Problem: Given the question: Due to increased carbon dioxide in the atmosphere more an more carbon dioxide is mixing with ocean water - thus increasing the acidity of the world's oceans. Rob is a climate scientist. He is measuring the acidity of the Atlantic ocean and the Pacific Ocean. To determine ocean water acidity he performed an acid-base titration. His conclusion is that Atlantic Ocean's acidity reached higher level than Pacific Ocean's acidity. In which ocean's acidity test the PH of the solution would not be that high as a result of lesser amount of added base, Atlantic Ocean or Pacific Ocean?
++++++++++++++++++++++++++++++++
The answer is:
Pacific Ocean
