Question

Frog, mountain goat and tortoise animals are belong to the same group.why or why not?

Answer 1

Answer:

Frogs belong to a group of animals called amphibians. Amphibian means two-lives.  Frogs begin their lives in the water as eggs and then tadpoles and when they are fully developed they live on land.

Amphibians are small vertebrates that need water, or a moist environment, to survive.

The mountain goat is an even-toed ungulate of the order Artiodactyla and the family Bovidae that includes antelopes, gazelles, and cattle. It belongs to the subfamily Caprinae, along with true goats, wild sheep, the chamois, the muskox and other species.

Tortoises are unique among vertebrates in that the pectoral and pelvic girdles are inside the ribcage rather than outside. Tortoises are reptile species of the family Testudinidae of the order Testudines (the turtles). They are particularly distinguished from other turtles by being land-dwelling, while many (though not all) other turtle species are at least partly aquatic.
