What is represented by the base root of a phylogenetic tree?
NeX [460]

The common ancestor.

A phylogenetic tree shows how a species originates (by evolution) other species. It’s very similar a genealogic tree. If you want your family tree, you should write down your name and the names of all your brothers and sisters and then draw a line from all those names to the names of your parents, and then draw a line from the name of your father to the names of your gramma and grampa, and then do the same with the names of your aunts and uncles. If you repeat the process with many, many generations, you will have the common ancestor to all of those relatives. You can do the same with species: for example, humans are supposed to have a common ancestor with monkeys, so their lines will end together in the same point in the graph. Then you have to draw a line from that point to another point that will be shared with other mammalians, then Mammalians share a point with other vertebrates, and so on… If you keep on going, you will get to LUCA someday.

How will you investigate a change in velocity affects the velocity of the two carts after the collision if the objects do not st
Nutka1998 [239]

P = mv

This is a momentum question:

Momentum is always conserved so the momentum before and after a collision must be equal so:

The velocity of the two objects after they collide and dont stick together if no KE is lost is dependent on the mass of each of the objects by:

m_{1} v_{1i} + m_{2} v_{2i} = m_{1} v_{1f} + m_{2} v_{2f}\\

Where i is initial and f is final meaning before and after the collision
