Answer:
A.
Explanation:
I've had to answer this before
A cladogram is a branching diagram that shows the cladistic relationship between a number species. It comes from the greek clados meaning branch and gramma meaning character. It is not to be confused with an evolutionary tree since it does not show the relationship between ancestors and descendants plus it also lacks the ability to show how they have changed over time. The major components of a cladogram are the tip (the start of the lineage), root (the end of the lineage) and node (where two or more lineages combine).
The answer is A because the subject is responding to something that is going on outside of it, if that makes any sense :)
Hope this helps! Have a great day!
It’s very confusing sorry for that
