Question

Read the passage. Then, select the text that best helps you understand the meaning of morphological. Costa Rica is Spanish for rich coast, and it's easy to see why: the tiny Central American nation is one of the most biodiverse places on the planet. Among its five hundred thousand species are fourteen different varieties of glass frog-tiny frogs thus named because some varieties have translucent skin on their abdomens. In February of 2015, herpetologists announced the discovery of a previously unclassified species of glass frog, which they called Hyalinobatrachium dianae. Morphological and genetic differences distinguish H. dianae from other Costa Rican glass frogs; however, more distinctive than either its appearance or its genome is its mating call, a pulsating whistle which more closely resembles that of an insect than that of any other glass frog.

Answer 1

The text that best helps understand the meaning of "morphological" is: "Morphological and genetic differences distinguish H. dianae from other Costa Rican glass frogs." This indicates that "morphological" relates to the physical form and structure of the glass frog, as it is being compared to genetic differences.
