It is a clear blue solution of sodium and copper salts. When heated with the food sample, the blue solution changes color to green, yellow, and brick-red, depending on the amount of sugar.</span>
Answer:
The correct answer is: mutualism
Explanation:
Mutualism refers to a relationship between two organisms, where both organisms benefit from the association. In this instance, the relationship between cellulose-digesting microorganisms and their hosts- termites and ruminant mammals- is characterized by mutualism because both organism benefit from their association. The microorganisms benefit by getting their nutrition from the cellulose in guts of their hosts. Whereas, the hosts benefit from the cellulose-digesting microorganisms by getting help in digesting the cellulose they consume in their diet.
Answer: C) The event at the end of the Triassic Resulted in the extinction of fewer fauna’s then in any other period
Explanation:
Looking at the graph, the event at the end of the Triassic resulted in the smallest dip in the amount of fauna in the graph. This means that this event resulted in the extinction of fewer faunas than any of the other five major events.
Option A is wrong as the event at the end of the Devonian decreased the number of Cambrian fauna.
Option B is wrong as the event at the end of the Cretaceous resulted in a decrease in the Paleozoic fauna.
Option D is wrong because the event that resulted in the Extinction of more fauna’s then in any other period was the event at the end of the Permian.
