Answer:
1. D.) Structural Data
2. C.) Overproduction
Explanation:
1. Structural Data was used to determine the similarities between the two species.
2. In biological terms, overproduction means that a generation had more offspring than can be supported by the environment. In this case, its a stronger hatchling beating out the waker hatchlings.
Granulated sugar dissolves faster than a sugar cube since it has a higher surface area. A sugar cube has a low surface which takes more time to dissolve.
Surface tension is defined as the tendency of elasticity of a liquid surface that makes it to achieve the possible least surface area. It depends upon the intermolecular forces present on the boundary of the surface of the compound and its contact.
n-butane 
is non-polar compound and it consist of only weak dispersion forces that are responsible for any contact with the surface.
In comparison to other given substances, n-butane has the weakest dispersion forces. Thus, n-butane has lowest surface tension.
