<span>The correct answer is B.Too much water moved into the cell. Similar things happen to our bodies, if there's too much water the body deforms because it becomes bloated. If there's too little water the body deforms and becomes smaller because there's no water so the skin shrinks a bit but it's barely noticable.</span>
Hey there,
D- an experiment that uses data to support or reject a hypothesis.
So basically its something that sums up everything that you did in the past.

The KT boundary marks a mass extinction event. the KT boundary is the time between the Cretaceous and Tertiary periods. An asteroid hit the earth at the end of the Cretaceous and that caused the end of the Cretaceous period. Before the KT boundary, pollen from angiosperms and gymnosperms is high. After the meteor hits the earth, a mass extinction occurs and the amount of pollen from gymnosperms and angiosperms decreases dramatically, while the amount of spores from ferns increases. During the Cretaceous period there were many species of gymnosperms and angiosperms but they disappeared at the KT boundary, when the asteroid hit the earth.
