Answer:
1.) stromatolites
2.) photosynthesis
3.) Ordovician
4.) Cambrian
5.) oxygen
6.) As Earth cooled, carbon dioxide dissolved in the early ocean. Cyanobacteria consumed carbon dioxide and converted it to oxygen. Methane was removed from the atmosphere as oxygen was produced, eventually leading to the Cambrian Explosion.
7.) Metabolic processes that use oxygen produce more energy than anaerobic metabolism. Simple diffusion of oxygen would limit the size of a multicellular eukaryote, but animals evolved ways to transport oxygen to their tissues, which permitted an increase in size.

Fossils are the remains or impression of the dead animals and plants that lived in the past.
The rapid change in the climate would potentially lead to ecological problems because evolution is unlikely to occur quickly enough to keep pace with biome changes.
<h3>What do you mean by Evolution?</h3>
Evolution may be defined as the process of growth and development or the theory that organisms have evolved and developed from past organisms.
Biome changes occur due to the fact of evolution. Both evolution and biome changes synergistically move forward to support organisms' life in a much better way.
Therefore, the rapid change in the climate would potentially lead to ecological problems because evolution is unlikely to occur quickly enough to keep pace with biome changes.

<span>The Correct answer is not shown. The correct answer would have to say Atom A has one proton than Atom B because in the question it says Atom A has an atomic number of 19 and Atom B has an atomic number of 20.</span>
