Answer:

Fossil records provide evidence of an increase in animal species at the same time that atmospheric oxygen levels increased.

Explanation:

A huge diversification among animal species occurred with the increase in the levels of atmospheric oxygen. The reason why the number of species increased drastically was that a whole new world opened up, the land. The land was open for exploitation and taking over, with every single niche free, so animals diversified and filled in pretty much all of the niches. The fossil records give us clues when this happened, as from only microorganisms there is a sharp rise in complex animals, coinciding with the increase of oxygen levels.

If it wasn't for the increase of atmospheric oxygen though this wouldn't have been possible. The oxygen in the atmosphere enabled animals to breathe on land. Also, it cooled off the global temperatures which were too high before the increase of atmospheric oxygen, making them suitable for life. And last but not least, the atmospheric oxygen resulted in the formation of the ozone layer, a layer that started to act as protection from the UV rays.

Answer:

When there are 5 molecules of fructose on each side of the membrane.

Explanation:

The solution will reach equilibrium fro fructose when there are 5 molecules of fructose on each side of the membrane.

A membranous system is said to be at equilibrium when there are equal concentration of a particular molecule on both sides of the membrane.

<em>Hence, for a membranous system with 10 molecules of fructose on one side, an equilibrium can only be reached for fructose when there are 5 molecules on one side and the remaining 5 molecules on the other side. </em>

2. Archean eon; toxic atmosphere; first bacteria

3. Proterozoic eon; buildup of oxygen; first eukaryotes

4. Phanerozoic eon; current eon in earth’s history

5. Paleozoic era; largest mass extinction in earth's history

6. Mesozoic era; time of the dinosaurs  

7. Cenozoic era; sometimes called "Age of Mammals"  

Eons are types of time division which are divided into eras, which are further subdivided into periods, epochs and ages. They include the Hadean eon, the Archean eon, the Proterozoic eon and the Phanerozoic eon. The Hadean eon, the Archean eon, and the Proterozoic eon are collectively called the Precambrian supereon.
