Mosasaurs were large marine reptiles that resembled a cross between a crocodile and a giant iguana. Completely dying out of these can be the illustration of extinction.
<h3>What is extinction?</h3>
Extinction is the dying out of a particular species. Extinction has an important role in evolution as it opens opportunities for emerging of new species.
The mosasaurs have completely died out after a big asteroid impact caused Earth to drastically change. This can illustrate extinction.
Thus, the correct answer is extinction.

B). They both contain nitrogenous bases.
Answer:
200 ATP molecules
Explanation:
Yeast is a fungus that undergoes fermentation instead of cellular respiration when there is an absence of oxygen. In the fermentation process undergone by yeast, which produces an alcohol as product (alcohol fermentation), two (2) ATP molecules are produced as net ATP.
However, if a yeast cell undergoes fermentation and uses 100 molecules of glucose, the yeast cell will generate a net ATP of 2 × 100 molecules = 200 molecules.
improved soil fertility
Explanation:
One direct benefit of biodiversity is improved soil fertility. Biodiversity is the variety of plants and animals living in a particular ecosystem.
A soli is made up of organic matter. Organic matter is the remain of dead and decaying plant and animal materials in the soil.
Organic matter is a very important soil component.
Since plants and animals eat up plants which takes nutrients from the soil, there must be a way to replenish these vital soil materials.
The more biodiverse an ecosystem, the better its chance of adding more nutrients to the soil as they decay.
