A high olecranon process locks the elbow into place when used in locomotion. This image of a human shows a dislocation of the ulna and you can see the olecranon process is low when viewed from this angle. What type of locomotion would benefit from having a high olecranon?
A. Suspensory
B. Quadrupedal
C. Vertical clinging and leaping
D. Bipedalism

One function of the poly-a tail on eukaryotic mrna sequences is to the mrna be transported from the nucleus to the cytoplasm. prokaryotic mrna also has a poly-a tail. choose the best explanation of the prokaryotic poly-a tail. a. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails. b. prokaryotic poly-a tails have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. c. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails have other functions, because prokaryotes don't have nuclei.
