Activation energy is required to start a chemical reaction. Activation energy is the energy needed to allow the reactant to react. Activation energy is measured in Joules (J).
Answer:
Is it likely that his body was moved after death? The answer is NO
Why or why not?
This is due to postmortem staining seen on his back which would have been observed on other parts of the body if the body was moved after death
Explanation:
Livor mortis: is the stage where the heart stops pumping blood through the circulatory system causing blood accumulation at the lowest point of the body. It's also called postmortem stain.
It helps in judging the time of death for a body, the location and position of the body if it's at the spot.
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.
I hope this helps, good luck!
