Answer:
C). Seafloor spreading.
Explanation:
Paleomagnetism is characterized as the 'study of the account of direction and strength of magnetic fields of the Earth in sediments, rocks, etc.' The hypothesis that was authenticated by using this study would be 'seafloor spreading' by displaying that magnetic reversal as strips of rotating polarity in gradually disseminating seafloor. This description of magnetic stripping by employing paleo-magnetism made the scientists believe that alternate crusts are being frequently made under ocean/sea. Thus, <u>option C</u> is the correct answer.

In animals and plants, there are two pairs of chromosomes - one set from a male and the other set from a female. But occasionally, the original fertilized cell doesn't quite divide correctly and more than two sets arises. The fertilized cell continues to divide with the result that all the cells have the extra set of chromosomes. This happens much oftener in plants and the plant will be sterile and can't form seeds.
To test for the keystone species hypothesis, the wolves in another region can be removed or trees can be reintroduced to see the effect on the ecosystem.
<h3>What is a keystone species?</h3>
A keystone species is an organism whose existence defines an entire ecosystem such that them, the ecosystem would be severely affected or may not exist.
Trophic cascades are events which result in serious distortions in an ecosystem as a result of the removal or addition of a top predator.
To test for the hypothesis of keystone species and trophic cascades, the wolves in another region can be removed or trees can be reintroduced to see the effect on the ecosystem.
