Answer:

A

Explanation:

I read about ocean tides. the Moon has an effect on the ocean which causes the ocean to bulge toward the Moon. When the Moon is in alignment with the sun the ocean bulges out more because of the added gravity. The Moon though smaller than the sun has more gravitational pull than the sun.

Basile [38]

Answer:

To describe a new specie, it has to be carefully examined in order to determinate that it doesn´t belong to an another specie already described.

Once it has been determinate the novelty of the specie, the researchers write a formal description of it, takes pictures and name it with the new scientific name. Then, the researchers refer it to a scientific magazine.   The editor of the publication will comunicate the new discovery to an experts in that gender.   If the experts agreed, and the publication accept the study, the specimen converts to a new specie.   The process is long and could take years betwen the inicial discovery and the formal acceptation of the new specie

Summarize the key factors DNA polymerase requires to replicate DNA.
vaieri [72.5K]

Answer:

Explanation:

DNA polymerase is an enzyme that helps in the synthesis of new strands of DNA. It is found in both prokaryote and eukaryotes. In prokaryotes, there are 3 types of DNA polymerase and more DNA polymerase found in eukaryotes.  

The 3 types of DNA polymerase are DNA polymerase I, DNA polymerase II, DNA polymerase III.  The DNA pol I and DNA pol II helps in DNA repair rather than DNA replication. The DNA pol III is the major enzyme that initiates the replication.  

DNA polymerase III is a multisubunit enzyme that functions as a dimer of these multiple subunits. The DNA polymerase enzyme has 3 significant enzymatic activities -  

All DNA polymerase direct the synthesis of DNA from 3' to 5' end.

It possesses 3' to 5' exonuclease activity. It also helps in proofreading activity by replacing the incorrect nucleotides with the correct base sequence.  

Some DNA polymerase has a 5' to 3' exonuclease activity. It is found in the lagging strand.

DNA polymerase is not able to initiate DNA synthesis alone. They need a free 3' end, where the enzyme can add new nucleotides. It means they require 2 primers to initiate the DNA replication in both the direction.  

The strands act as complementary to the DNA polymerase. The DNA polymerase adds new strands continuously in 5' to 3' direction in the leading strand. While in lagging strand short fragments of DNA formed. Later they attached by DNA ligase.

DNA polymerase also needs RNA polymerase in some cases to start replication. Such a process is called reverse transcription.

snow_tiger [21]
Chronic backache

<span>The nurse should provide preventive measures for chronic backache as a consequence of lordosis when caring for this client. Chloasma is characterized by darkened areas on the face, particularly over the nose and cheeks. It is also known as the mark of pregnancy. Chloasma is not caused by lordosis. Diastasis occurs as the pregnancy progresses when the rectus muscle stretches to the point that it separates. It is not caused by lordosis. Edema in lower extremities occurs due to an impeded venous return caused by pressure of growing fetus on pelvic and femoral areas. It is not caused by lordosis.</span>
