Being made of pyrex or other borosilicate glass, a conical flask can be used for heating (or cooling) liquids without much risk of cracking. Often a solution is made up by adding a solid to a liquid in a conical flask, and sometimes heating it. A magnetic stirrer can be added to keep the mixture swirling.
Since the neck is narrow and the body is wide, there is less tendency for liquids to splash out of the top when swirling, compared to a beaker. This is great if there are strong acids or bases in it. The narrow neck also makes a conical flask easier to pick up than a large beaker.
The difference between a conical flask and a round bottom flask, is that the conical flask has a flat bottom, so can be put down on any surface. They are also easier to clean than a round bottom flask, as they don't have such an obtuse angle between the neck and bulb.

Explanation:
True toads" make up the Bufonidae family, which includes 580 species. Frogs and toads do have specific traits that define them, however, according to the Maryland Zoo. For example, frogs are mostly aquatic; most toads live on land (but near water). Frogs have teeth; toads do not.
