8 0

Answer:

D. Spanned from about 3.8 billion to about 2.5 billion year ago

Explanation:

The Archean eon expanded from 4 billion years ago, until 2.5 billion years ago, being predeceased by the Hadean eon, and being followed by the Proterozoic eon. During this eon there were numerous very important things that happened. The first solid rocks were formed, thus the basis for the first continents arrived on the scene. The oldest fossils of living organisms are also dated to this eon, and they were the ones that started to slowly change the atmosphere by introducing free oxygen molecules to it.

Andreyy89

Explanation:

Cardiac muscles are one of the three muscles found in the human body (the other two being skeletal and smooth muscles). It is the only type of muscle found in the heart. Cardiac muscle cells have a single nucleus unlike the skeletal muscle cells.

They possess many large mitochondria in their cell, which enable them actively carry out the process of aerobic respiration. The cardiac muscles contains an enormous amount of myoglobin pigment, which enable them store and transport oxygen.
