question 11
what feature of a phylogenetic tree shows a group of organisms that evolved from a common ancestor?
branch
host
tree
clade

Explanation:

In a phylogenetic tree, a clade is defined as a group of organisms that includes an ancestor and all of its descendants (organisms that evolved from that common ancestor). A branch represents the evolutionary lineage but not the defined group from a common ancestor. "Host" is not a feature of a phylogenetic tree related to this concept, and "Tree" is the overall structure, not the specific group. So the correct answer is Clade.

Answer:

D. Clade
