According to the fossil record found in these sedimentary layers, what conclusion can be drawn about animal life in general?

Missing options are

A). Animals did not move on to land until flowering plants evolved.

B). Vertebrates appeared in the oceans before they moved on to land.

C). Vertebrates evolved on land and in the oceans at about the same time.

D). Shelled animals and fish appeared in the oceans at about the same time.

The correct answer is B: Vertebrates appeared in the oceans before they moved on to land

Explanation:

The first vertebrates were fish (hagfish) and they appeared on Earth nearly 525 million years ago. During the Devonian period, 419 to 358 million years ago, they were evolved to tetrapods vertebrates (amphibians) that lead to the development of life in terrestrial habitats. These animals adapted the terrestrial environment by developing column, jaws, and a bony endoskeleton that also helped then survive against gravity. Therefore fossil record about terrestrial life is present after marine vertebrates evolved to land vertebrates.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
