This phylogenetic tree shows how scientists believe the danes, chinese, and tibetans are related based on the analysis of many genes. use the data about the epas1 alleles to add information to the tree. (assume that there is no interbreeding between the different populations after the lineages split.) labels can be used once or more than once.

Atypical human cell is approximately 12.00 μm in diameter and enclosed by a membrane that is 5.000 nm thick. (a) what is the volume of the cell including the membrane? (b) what is the volume of the cell membrane? (c) what percent of the total volume does its membrane occupy? to simplify the calculations, model the cell as a sphere. enter your answers using four significant figures.
