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.
Answer:
Active transport requires cellular energy to achieve this movement. There are two types of active transport: primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient.
4 Types:
1. P-type ATPase: sodium potassium pump, calcium pump, proton pump
2. F-ATPase: mitochondrial ATP synthase, chloroplast ATP synthase
3. V-ATPase: vacuolar ATPase
4. ABC (ATP binding cassette) transporter: MDR, CFTR, etc.

Answer:
The beetles gland stores enough hydroquinone and hydrogen peroxide to allow the beetle to release its chemical spray roughly 20 times. Thus pulsed mechanism is beneficial for the beetle survival because the system uses pressure instead of muscles to eject the spray at a constant velocity, saving the beetle energy.
