and on top of lakes and ponds. This is pollution he can see. Does Emmerson's experiment support this
claim? Explain your answer.

Answers

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 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.

Lucille was finding it difficult to play soccer after school. Her doctor tested her cells and found that they contained low levels of oxygen. When Lucille shared these results with a friend, her friend said there might be a problem with Lucille’s respiratory system.

What do Lucille’s cells need in order for her body to function properly? How might a problem with Lucille’s respiratory system lead to low levels of oxygen in her cells? Why does having low levels of oxygen in her cells make it difficult for Lucille to play soccer?

Answers

Answer:

The Lucille’s cells need Oxygen and glucose in order to function her body properly.

Explanation:

Our body breakdown the glucose using oxygen in order to produce energy.

By respiratory system we inhale oxygen and

By digestive system we digest food into glucose.

Our circulatory system transfer the Glucose and Oxygen to the all cells of our body,

Hence we can conclude that the Lucille’s cells need Oxygen and glucose in order to function her body properly.

Do you think the Oklahoma City events described in the article give adequate proof of the scientists concerns? Explain why or why not.

Answers

Answer:

Yes, these events give adequate proof. Some residents of Oklahoma City panicked during a tornado. They chose to flee rather than seek shelter. Thousands of people were stuck in a massive traffic jam. Fortunately, the tornado did not hit the highway. If it had, the people trapped there would have been in great danger. Cars offer little protection from a tornado.

Explanation:

Plato/Edmentum Answer

Answer:

Yes. Some people from Oklahoma City started to panic when the tornado hit. And instead of looking for shelter they decided to run and so then a lot of people were stuck in traffic. If the tornado hit the highway where are the traffic was, which luckily was not, but the people there would've been taken by the tornado and cars do not protect you from the tornado that much.

Eukaryotic DNA

Answers

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 process

DNA 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 process

The 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  

This enzyme works in the replication origin breaking the hydrogen bonds between nitrogenated bases pairs

It separates the DNA into two strands allowing the replication forks to advance by unwinding the DNA.  

DNA polymerase I and III

Enzymes that are in charge of DNA elongation by adding nucleotides.

They synthesize the new strains.

They correct mistakes produced during the synthesis.

Endonuclease

In charge of eliminating mistakes.

They cut the erroneous segment.

DNA ligase seals the gaps that remain after cutting segments.
