Answer:
The invasive s p e c i e s tend to diminish the populations of native s p e c i e s because they outcompete them, and also manage to disturb the ecosystem.
Explanation:
The invasive species can or cannot be dangerous for the native biodiversity, but unfortunately, it is the second one that is much more common. The reasons as to why the invasive species tend to threaten the biodiversity are that they often don't have a native predator that will control their numbers, outcompete the native species for resources, and the native species don't have defense mechanisms against them. These factors result in havoc in the ecosystem in a relatively short period, with the potential to totally destroy it and changed it.
There are thousands of examples of invasive species around the world, some much more obvious than others. The Burmese pythons in Florida for example, have started to overtake the a p e x predator niche from the alligators by directly attacking them. On the other side of the world, in Australia, the cats and rabbits have contributed to leading hundreds of native species on the verge of extinction, and if there hasn't been human intervention there is a very high chance that a lot of native species would have been already extinct.
One thing scientists in the late 1700s could determine about the fossils they were finding were fossils in the upper layers were younger than fossils in lower layers. The correct answer is A.
Angles in a triangle add up to 180 degrees.
180 - 125 = 55
Add the ratios 4+7 = 11
Divide the left over angels by the ratio: 55/11 = 5
Now multiply 5 by each side of the ratio:
4:7
4*5 = 20
7*5 = 35
So the 2 angles are 20 and 35 degrees.
To check, you can add up all the angels : 20 + 35 + 125 = 180
So we know 20 and 35 is correct because it adds up to 180 degrees :)
Answer:
Smallpox has had a major impact on world history, not least because indigenous populations of regions where smallpox was non-native, such as the Americas and Australia, were rapidly decimated and weakened by smallpox. During the 18th century the disease killed an estimated 400,000 Europeans each year, including five reigning monarchs, and was responsible for a third of all blindness. After successful vaccination campaigns throughout the 19th and 20th centuries, the WHO certified the global eradication of smallpox in December 1979. Smallpox is one of two infectious diseases to have been eradicated.
