The correct answer is: Events that occur early in the fossil record are represented by branching events nearer to the root of a phylogenetic tree.
Fossil records explain the history and evolution of life based on fossils. Fossils are remains of organisms preserved in sedimentary rock. In fossil records they are analyzed and arranged chronologically and in taxonomic order, so that can represent the evolution.
Phylogenies describes the relationships between organisms (species): from which organisms it is evolved, to which species it is most closely related etc. and it is represented as a diagram or phylogenetic tree. It is used to organize living organisms into specific categories. Characteristics of fossils are used to generate a phylogenetic tree, more precisely their roots that represent common ancestors.

Answer:
The vacuoles are different sizes.
Explanation:
Orthopneic
The client's paroxysmal dyspnea was probably caused by sleeping in bed with the legs at the level of the heart; this position increases venous return from dependent body areas, increasing the intravascular volume. Sitting up and leaning forward while keeping the legs dependent slows venous return as well as increases thoracic capacity. Although the contour position elevates the client's head, it does not place the legs in a dependent enough position to substantially decrease venous return. The recumbent position is contraindicated. Venous return increases when the lower extremities are at the level of the heart. Also, the pressure of the abdominal organs against the diaphragm decreases thoracic capacity. The Trendelenburg position is contraindicated. Venous return increases when the lower extremities are higher than the level of the heart. Also, the pressure of the abdominal organs against the diaphragm decreases thoracic capacity.
