BIOLOGY! 20 POINTS! ANSWER ASAP! What does the red node represent? (CHOOSE ALL THAT APPLY) (see photo)

1.)The common ancestor of species B and C

2.)The common ancestor of species A, B, and C
AR

3.)The common ancestor of species A and B

4.)A speciation event

The red node represent a speciation event  and the common ancestor of the species  B and C i.e option 1 and 4 are the right answers.

Explanation:

Speciation is an event that leads to splitting in a lineage producing two or more species. The speciation would lead to different species as they no longer can interbreed and produce viable offspring.

The node shows that the two species originated from the same root but undergone speciation to be two different species.

The speciation takes place due to genetic drift, selective breeding and mutations in the population which lead to Natural selection.

In the given picture the root with trait one got modified into trait 4 and 5 via trait 3. This means that due to mutation the genes have changed and evolved for better functions and thus they survived via Natural Selection.

The figure represents diverge population as two new species are there and thus is Allopatric Speciation and have common ancestors.

ask your friends for what they got then copy it down if you don't have any friends which is fine than google it or pay the teacher
