Dr. Digger, a paleontologist, finds a fossil that he describes in his journal. The creature was approximately 1 meter long, with its backbone fused into a large shell covering the body cavity. It had a beaklike mouth, without teeth, and all four limbs were in the form of flippers.

Based on anatomical similarities, to which modern animal is Dr. Digger’s creature most closely related?

It's speed of rotation.

Ithink all of these events

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.
