1. Mammals are one of the most diverse classes of Chordates. Both the skeleton and the diet have
played a key role in the radiation of this diverse class. Describe specific skeletal changes
(address bones from head to toe) and dietary categories (address teeth types and digestive
tracts) that have separated the class into distinct taxa. Give examples of herbivores, omnivores
and carnivores, and specific animals that possess these traits. Include any specializations which
may have occurred in their body plans to support their needs.

If you have a difficult time knowing where your hand is without looking at it you may be having a problem with your what ?

In which situations is the principle of cross-cutting relationship useful in determining relative age?

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.
