Question

Where is the world's most active volcano located ? How did life begin in the universe and how can whales be considered as mammals ?

Answer 1

Answer:

Kilauea volcano on Hawaii is the world's most active volcano

The earliest known life-forms on Earth are putative fossilized microorganisms, found in hydrothermal vent precipitates, that may have lived as early as 4.28 billion years ago, relatively soon after the oceans formed 4.41 billion years ago, and not long after the formation of the Earth 4.54 billion years ago.

Whales are mammals because they give birth to live young
