Final answer:
Based on their binomial names, Quercus alba and Quercus rubra are from the same genus but are different species, indicating they do not belong to the same species.
Step-by-step explanation:
Based on the binomial names Quercus alba and Quercus rubra, we know they do NOT belong to the same species.
The binomial nomenclature system gives each organism a two-part name, with the first part indicating the genus name and the second part the species identifier. Since both trees have the genus name 'Quercus', they belong to the same genus and are also likely to belong to the same family, Fa-gaceae, a classification level above genus. They are different in species based on their unique second name; 'alba' means white and 'rubr**a' refers to red, suggestive of distinct characteristics.
