Question

1. a large island in the pacific ocean supports isolated populations of two groups of frogs. the following observations of these frogs were recorded by scientists.

which observation best supports the inference that these frogs belong to the same species?
(a) are different in color
(b) excrete different products
(c) live in different, isolated habitats
(d) can interbreed and produce fertile offspring
a) a
b) b
c) c
d) d

Explanation:

To determine if two frog groups are the same species, the key is whether they can interbreed and produce fertile offspring (biological species concept). Option D directly addresses this. Options A (color), B (excretory products), and C (habitat) don't define species.

Answer:

D. Can interbreed and produce fertile offspring
