Answer: UPPER BODY is ur answer
When it comes to gas exchange, it is important to note that oxygen is transported from the lungs to the rest of the body via the circulatory system, and oxygen-rich blood flows back to the heart from the lungs.
What is the circulatory system?The circulatory system is responsible for transporting blood throughout the body. The heart, blood vessels, and blood make up the circulatory system.
The circulatory system's role in gas exchange: The circulatory system plays an important role in the gas exchange process. The heart pumps oxygen-rich blood from the lungs to the rest of the body, where it is used for various functions.
After delivering oxygen to the body's tissues, the oxygen-poor blood flows back to the heart, where it is sent back to the lungs to be oxygenated once again.
In conclusion, the oxygen-rich blood is flowing from the lungs to the heart.

Why do you think so many codons code for the same amino acids what benefit might this provide to organisms on earth
Answer:
Many codons code for the same amino acids and the advantage of this phenomenon in organisms is the reduction of deformities and damages caused as a result of mutations.
This means if a mistake or mutation happens during translation there is a great chance of it not having grave consequences on the organisms because the altered codon will still code for the same amino acid and doesn’t disrupt the processes this is to be undergone.

Explain some of the evidence that supports the scientific theory of evolution. Examples can come from fields such as comparative anatomy, fossil record, comparative embryology, etc.
Answer:
Origin of Species was a book that was published in 1859 by Charles Darwin on human evolution. This theory was based on natural selection.
Explanation:
The evolution theory was first proposed by Darwin in 1856 in his book Origin of Species. In this theory, Darwin explains the changes in species over time result in the changes in the traits and heritable qualities. Evolution occurred by natural selection. In this theory, scientists show two main points that, all species are connected on this earth and the diversity in the population is the result of the modification in traits by time.
For Example, one study on 1900 students on human evolution was published in the journal " Personality and Individual Differences". According to this research, people are hard to find their soul mate because the changes are very rapid in traits.

blood vessels that contain valves and rely on skeletal muscles to move blood are called:
A) arterioles
B) veins
C) capillaries
D) arteries
and why!? thanks!!
Answer:
veins because they carry low pressured blood due to which there is more chance for backward flow of blood and to prevent that they contain valves.
hope it helped uh..
Answer:
B. Veins
Explanation:
Veins carry blood relying on the action of the skeletal muscle as the body moves. Veins have valves so blood flows in only one direction. Valves are not present in arteries. Arterioles is small and contains valves to prevent backflow of blood but does not rely on skeletal muscles. Capillaries don’t have any valves. The correct answer would be veins.
