- The Rate Of Neutral Substitution Can Be Measured From Divergence Of Repeated Sequences
KEY CONCEPTS:The rate of substitution per year at neutral sites is greater in the mouse than in the human genome.We can make the best estimate of the rate of substitution at neutral sites by examining sequences that do not code for protein. (We use the...
- #48 Summary Of The Mammalian Heart
1 The human heart, like that of all mammals, has two atria and two ventricles. Blood enters the heart by the atria and leaves from the ventricles. A septum separates the right side of the heart, which contains deoxygenated blood, from the left side,...

Today we did a heart-rate lab and I met a new person named Tiffany. The lab was easy and interesting since I got to walk around the classroom. Also, Mrs.Tyrell showed us Tuger Salamanders that at just so cute...
