Just in case that the Arab-Israeli war did not occur in the year 1967, what would happen is that the Palestinians would become Jordanian citizens. This answer is based on the actual options attached to this question.
Answer:
TRUE
Explanation:
The scientists examine the change in the magnetic field of the earth to determine the age of the ocean floor. Once in a while, the currents in the core of the ocean which create the magnetic field on the earth, are reversed. This is known as a geomagnetic reversal.
When the magnetic data of the sea floor was studied, they discovered about the normal and the reversed magnetic stripes.
The geomagnetic reversals records was matched with the stripes of the normal and the reverse magnetic fields, to determine the age of the ocean floor.
<u>Therefore, the give statement is TRUE.</u>
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.
