Answer:
Phylogenetics
Explanation:
An evolutionary tree can also be called a phylogenetic tree, or a just a phylogeny, and phylogenetics is the study of determining evolutionary relationships, or patterns of descent of organisms.
Hope it helps...
Surface area of the cell=4x pix2^2=50.3 um.
Volume= 4/3 x pi x 2^3=33.5 um
Ratio= 50.3/33.5=3:2
