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.
Then the four seasonal periods will be twice as long as they are now.
C. would be it, hope this helps!
Answer: a. perigee speed
Explanation:
Firstly, we must define what is Perigee and Apogee:
The apogee is the point in an elliptical orbit around the Earth <u>where a body is furthest from the center of it and according to Kepler's 2nd law the speed of a satellite at this point is the lowest.
</u>
On the other hand, the <u>perigee</u> is the opposite orbital point. <u>It is where a satellite is closest to Earth and its orbital speed is maximum.
</u>
Therefore, if we want to throw an object in such a way that it is orbiting the Earth at the same distance respect to the ground, the minimum speed must be that which is in the perigee.
