What two enzymes are used during replication and what does each do?
Answer:
The two enzymes that are used during DNA replication is helicase and polymerase. Each enzyme has distinct role that made it a vital part of the replication. In the course of DNA replication, the initial stage is to unzip the double helix structure of the DNA molecule by the enzyme helicase, which breaks the hydrogen bonds that holds the complementary bases of DNA.
Moreover, the DNA polymerase has the ability to exactly copy a DNA template. This enzyme binds to the leading strand and then adding a new complementary nucleotide bases to the DNA strand. In addition, it catalyzes the joining of deoxyribonucleoside 5′-triphosphates (dNTPs) to form the increasing DNA chain.

Samira watched a demonstration in which a scientist combined two substances in a sealed container and analyzed the results. The ending substances did not look the same as the starting substances.
Samira was given a diagram with the repeating groups of atoms that make up the starting substances, plus information about the properties of the starting and ending substances. She created a model of the repeating groups of atoms that might make up the two ending substances.
A.) Does her model correctly show why the properties of the ending substances are different from the properties of the starting substances?
B.) Describe what could be correct or incorrect about her model
Look at the diagram below then write your answer to question 13 part "A" and "B".
THIS IS NOT A MULTIPLE CHOICE QUESTIONS YOU NEED TO ANSWER BOTH QUESTIONS
thanks
Answer:
hope its not to late..............Samira's model correctly demonstrates how the properties changed with the rearrangement of the atoms. However not all atoms are accounted for. There is a missing reactant. Samira's model correctly demonstrated how the atoms in two compounds reacted to form two new products. However, the elements present in the reactants side should be the elements that make up the new products in the product side. But as the diagram shows, Sameera has mistakenly added a new element to one of her products which will be wrong.
Explanation:
Groups/Families are arranged vertically in different columns on the periodic table of elements. These groups/families have similar properties and chemical behaviors.
True
False

Write an explanation of the relationship between genes, proteins, and traits for the Blue Lobster.
You may think of a lobster as red, but about 1 in every 2 million lobsters is blue! This blue color is the result of a mutation in the lobster’s genes. The mutation causes the lobster to make an extra amount of a protein called astaxanthin. This protein is usually important for the red color that you see when the lobster is cooked, but in excess amount, makes the lobster blue.
Answer: The lobster's blue coloration is a result of a genetic defect that causes the lobster to produce more of a certain protein than normal.
On the following periodic table of elements, what do these colors represent?
blue - -Nonmetals
red- -Metals
yellow- -Metalloids
Answer:
blues are nonmetals (gas)
yellows are metalloids (liquids)
reds are metals (solids)
Explanation:
good luck, hope this helped <3
Why do scientists track virus mutations and how might tracking these variants be helpful in preventing and treating the virus?(coronavirus)
Answer:
Different variants = certain symptoms and effects of the virus that cannot be prevented by the "basic" or "original" vaccine. So tracking the different variants would allow scientists to also account for those effects when creating a 2.0 vaccine or treatment.
Scientists track the coronavirus and its mutations around the world to study and fight it properly.
The coronavirus is a virus that became a pandemic during 2020 that spread throughout most of the planet, infecting millions of people. People who acquired the virus had symptoms of respiratory infection such as
CoughTrustworthyBody painChillLoss of smellIn its expansion, the virus mutated into different variables, this meant a challenge for the scientists in charge of combating it because its variables could have characteristics of the first variant, making it more difficult to eliminate.
Therefore, the scientists emphasized protection to avoid contagion and the variants that emerged were studied in depth to verify that the treatments that were being developed worked for all the variants.

write a sentence that describes how the flow of liquid with low viscosity differs from the flow of a liquid with high viscosity
Answer:
Fluids with low viscosity have a low resistance and shear easily and the molecules flow quickly; high viscosity fluids move sluggishly and resist deformation. Some liquids, like pitch, glass and peanut butter, have such high viscosity they behave like solids.

Please answer the question in the image provided
Answer:
Gold
Explanation:
In order to find the density, just divide the mass by volume using the formula d=m/v.
d = m/v
d = 38.6/ 2cm^3
19.3 = 38.6/2cm^3
Look back at your chart and see which substance is 19.3, which is gold

What codes for proteins?
(A.) RNA
(B.) DNA
(C.) amino acids
(D.) polypeptides
Answer:
The answer is RNA
Explanation:
Each sequence of three nucleotides, called a codon, usually codes for one particular amino acid. (Amino acids are the building blocks of proteins.) A type of RNA called transfer RNA (tRNA) assembles the protein, one amino acid at a time.
Answer:
(A.) RNA
Explanation:
The type of RNA that contains the information for making a protein is called messenger RNA (mRNA)
