Answer:
The nucleus
Explanation:
Imagine the nucleus as a brain. Differsnt parts of the lobe has a part that controls you. The brain controls what you hear, see, move, how to "process" infomation, and how to remember the what you did or learn. The brain and nucleus don't funtion the same but they fall into the same categories of control.

A. become CO2 and H20, become part of the body
B. become part of the body, are lost as CO2 and H2O
C. become C6H1206, become ATP
D. become ATP, become C6H1206
Molecules used for growth and repair and molecules used for energy become C6H1206, become ATP.
What type of molecules are used for energy and growth?
ATP, or adenosine triphosphate, is the most frequently used transit molecule that quickly carries usable energy around and inside cells. It is used for cell growth, like mitosis.
What two types of molecules in cells are used to supply and store energy?Glucose and other food molecules are broken down by controlled stepwise oxidation to provide chemical energy in the form of ATP and NADH.
What molecules can be used for long term energy storage?Lipids are molecules that can be used for long-term energy storage.

Give all the possible Anti-codons for the amino acids listed below. (Use page 244 in your text). Histidine (His)
Given what we know about the genetic code, we can confirm that the anticodons recognized as Histidine are GUG, CAC, and CAU.
When a protein is synthesized, the cell reads the genetic code on the mRNA strand and uses tRNA to bring the corresponding amino acids together, thus creating the desired protein. This code is not unique however, what this means, is that more than one grouping of nucleotides (codons) can code for the same amino acid.
This helps to explain how there are 26 amino acids, and yet there are over 60 possible combinations of codons. Through careful study, scientists have been able to uncover that the amino acid histidine can be called by 3 distinct groupings of nucleotides. These are:
CACGUGCAUeach of which will cause the tRNA to bind to histidine.

Prokaryotic DNA
Eukaryotic DNA
There are a few differences between the prokaryotic and eukaryotic replication processes. However, both of them include the general same steps. 1:Replication fork/2:Unreplicated DNA/3:Origin of replication/4:New DNA
--------------------------
Eukaryotic DNA replication processDNA Replication starts in some specific place named replication origin. Eukaryotic cells have many replication origens.
Helicase
This is the first enzyme that works in the replication origin. It separates the DNA into two strands allowing the replication forks to advance by unwinding the DNA. It breaks hydrogen bonds between nitrogenated bases pairs.Topoisomerase impedes the DNA double helix near the replication forks to get too coiled when the DNA is opening.
DNA polymerase III
This enzyme is responsible for DNA elongation. It is in charge of adding nucleotides to the growing chain, from 3' to 5' extremes.It includes only nucleotides that complement the original strand. They need to recognize a primer to begin.
Primase is in charge of synthesizing primers.
DNA polymerase I eliminate ARN primers and substitute them with DNA.
DNA ligase seals the gaps that remain after replacing the primers.
*************************************
Prokaryotic DNA replication processThe prokaryotic replication process involves the double helix unwinding and opening from an origin point, which is the replication origin.
Prokaryotic cells only have one replication origin.
Proteins DNA A
They recognize the replication origin and are responsible for the beginning of the process.
Helicase

What is scientists?A scientist is a person who collects data methodically and uses it to generate hypotheses, test those ideas, and advance knowledge and understanding. The approach of a scientist, such as the use of statistics or data, can also be utilized to further define them.
In his anonymous 1834 Quarterly Assessment review of Mary Somerville's On the Connexion of the Physical Sciences, English philosopher and historian of science William Whewell used the term "scientist" for the first time in literature.
A scientist is an expert who conducts and gathers research to increase knowledge in a certain discipline. Scientists might come up with hypotheses, test them with information and other tools like statistics, and then make judgments based on the findings.
Thus, Duordon is a genius of extinct.

Emmerson concludes that nearly all water pollution takes place in surface water-water on the ground
and on top of lakes and ponds. This is pollution he can see. Does Emmerson's experiment support this
claim? Explain your answer.
Yes Emmerson's experiment supports this claim, the reason is because in the he did not made a general conclusion he said "nearly all" and in the experiment he was specific to surface water pollution, hence highlight the fact that there is also a case for deep water pollution that "he can not see"
What is surface water Pollution?
This can be defined as a type of water pollution in which pollutant occurs above the ground, like in streams, rives, oceans, it is basically caused by excessive nutrient found in waterways that leads to the growth of algae
