About______ the first cellular forms of life appeared on earth.
1 3000 (mya)
2 2000 (mya)
3 2000 (bya)
4 3000 (bya)
Explanation:
The first cellular form of life originated about 4 billion years ago. 3 billion years ago, 2000 million years ago and 50,000 years ago is after the origination of life on earth. So, before 4 billion years ago, cellular form of life did not possibly originated or present.

Which of the following is incorrect?
1 Lobefin fish evolved into first amphibians.
2 Ichthosaurus evolved about 200 mya.
3 Stegosaurus was 20 feet in height and had huge fearsome dagger like teeth.
4 Reptiles of different shapes and size dominated on earth around 200 mya.
Explanation:
Tyrannosaurus rex was 20 feet in height and had huge fearsome dagger like teeth. Lobefin fish evolved into first amphibians. Theses fish had thick and stout fins, and could move on land move back to water. Around 200 mya, some reptiles went back to water and developed fish like characters, to form ichthyosaur. Reptiles of different shapes and sizes dominated on earth around 200 mya. Mesozoic era is called age of reptiles.

The ancestors of modern day frogs and Salamanders are
1 Jawless fish
2 Coelocanth
3 Icthyophis
4 Amphioxus
Explanation:
In 1938, fish caught in south Africa happened to be a Coelacanth which was thought to be extinct. These animals evolved into the first amphibians that lived on land and water. These were ancestors of modern - day frogs and salamandes
