4. The two major threats of burns are? a. Loss of skin and infection
b. Dehydration and Discoloration
c. Discoloration and Loss of Skin
d. Infection and Dehydration

A

Explanation:

Id say A because dehydration has to do with the lack of water, and we are talking about burns. Discoloration might make sense in context such as the skin around the burn was dark and discolored. But actually loosing your skin and getting an infection in that open wound sounds much worse

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.
