Answer:

B. Their predators have been killed by the Cretaceous-Paleogene extinction

Explanation:

The mammals and the avian dinosaurs were small creatures, living in the shadows of the dinosaurs which dominated the world, but also were stopping the further increase in size and development of these animals. At the end of the Cretaceous though, an asteroid struck the Earth. The impact was so hard and devastating that it managed to destroy the dinosaurs and wipe them out of the face of the Earth, with the only dinosaurs remaining being the small avian species. Since lots of niches opened up and where free for taking in the ecosystem, the mammals and the avian dinosaurs quickly started to evolve, diversify, and become much larger. The mammals seem to won the race for dominance as they have become the most dominant species on the planet.

3 Countries with Gold

1. China

2. Russia

3. Australia

Explanation:

1. Iraq's petroleum industry is very important for its economy. Before its international embargo, it became a major exporter of crude oil.

2. Iran has one of the largest petroleum reserves in the world. Just like Iraq, it also became a major exporter of crude oil. However, due to wars and sanctions, export revenue declined.

3. Kuwait is a tiny country that is rich in oil. It's largest industry is "petroleum industry," and it is owned by the government.

4. China is considered to be the largest gold-producer in the world. Although it only has a few gold reserves, many people are into gold-mining.

5. Next to China is Russia. It is second when it comes to the accumulation of gold, yet it is only in 6th position when it comes to gold reserve.

6. Australia is perceived to overtake China's position in the coming years as the largest producer of gold in the world. This is because of Australia's cost-effective mining and plans for major expansion.

How does a closet Lake differ from an open Lake

Sidana [21]

open lake is a lake where water constantly flows out under almost all climatic circumstances. Because water does not remain in an open lake for any length of time, open lakes are usually fresh water: dissolved solids do not accumulate. Open lakes form in areas where precipitation is greater than evaporation. Because most of the world's water is found in areas of highly effective rainfall, most lakes are open lakes whose water eventually reaches the sea.

closed lake (see endorheic drainage), no water flows out, and water which is not evaporated will remain in a closed lake indefinitely. This means that closed lakes are usually saline, though this salinity varies greatly from around three parts per thousand for most of the Caspian Sea to as much as 400 parts per thousand for the Dead Sea. Only the less salty closed lakes are able to sustain life, and it is completely different from that in rivers or freshwater open lakes.
