Answer:

It's a Bilayer

Explanation:

<em>The lipid bilayer (or phospholipid bilayer) is a thin polar membrane made of two layers of lipid molecules. ... The cell membranes of almost all organisms and many viruses are made of a lipid bilayer, as are the nuclear membrane surrounding the cell nucleus, and membranes of the membrane-bound organelles in the cell.</em>

Constructing phylogenies is not as simple as grouping organisms with similar characters together. Identify situations in which s
Dmitrij [34]

Answer

similar characters evolved owing to convergent evolution; similar characters are ancestral

Explanation:

Convergent evolution happens when two organisms belonging to different species, living at different times or different continents but the same biome develop analogous structures hence making them appear similar.  The analogous structures were not present in the known ancestors of both groups.

Therefore convergent evolution is ignored during constructing phylogenies

Also similar characteristics that are ancestral are ignored.
