Answer: It makes the DNA molecules split up into two separate strands of DNA.
An enzyme is a protein that facilitates certain cell processes makes the DNA molecule split up into two strands.
What does this enzyme (helicase) do to the DNA molecule?
DNA moves the nitrogenous bases, helping them to attach to the proper molecule. Complete the 2 molecules of DNA by dragging nucleotides to their corresponding locations.
The DNA enzyme helicase unzips the DNA strand in order that one side is often used as a template to form a replacement strand. DNA polymerase is another enzyme that takes nucleotides from the solution and bonds them to other nucleotides.
DNA helicase unwinds the double helix at the replication fork.
Therefore, the DNA molecule split up into two strands.

Which statement is correct regarding the semiconservative nature of DNA?
A. RNA operates as a template to allow DNA to replicate itself using ribosomes
B. Nitrogenous bases in each "parent" strand serve as a template for the new strand to be made
C. The semiconservative nature of DNA allows for genetic continuity in gamete production
D. The structure of the sugars on the DNA molecule direct the correct nucleotides into place during replication
I need the answer fast, this is a 40 point and i will put you as brainliest
Answer:
B. Nitrogenous bases in each "parent" strand serve as a template for the new strand to be made
Explanation:
DNA replication is the process whereby the contents of DNA is doubled or duplicated. In other words, another copy of DNA is produced from one DNA molecule. The process follows the semi-conservative model, which generally speaks of how one template strand is used to synthesize another new strand.
In the semi-conservative model of DNA replication, the double strand of DNA is unwind and one of the strands called parent strand is used synthesize a complementary strand of DNA. At the end of the process, two DNA molecules results with each having one old strand and one new strand. Nitrogenous bases or nucleotides in each "parent" strand" serve as a template for the new strand to be made.

How does having genes on many chromosomes, rather than on just one chromosome, increase genetic variation among offspring?
Answer:
Genetic variation is increased by meiosis
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. ... A gamete will end up with 23 chromosomes after meiosis, but independent assortment means that each gamete will have 1 of many different combinations of chromosomes
Explanation:
Due to the possibility of genetic material being recombined and shuffled during meiosis, having genes on several chromosomes as opposed to only one chromosome enhances genetic variety among kids.
What is genetic variation among offspring?At locations known as chiasma, the chromosomes overlap. The chromosomes split and reunite at each chiasma, exchanging part of their genes in the process. Genetic diversity comes from this recombination.
The chromosomes align in pairs and cross over during the meiotic process to exchange genetic material. This process results in novel gene pairings on the chromosomes, which can result in the birth of kids with distinctive combinations of features.
Therefore, the possibility of genetic material being recombined and shuffled during meiosis increases genetic variation among offspring.

there are more hydrogen atoms in living organisms than any other atom, but oxygen is more abundant in terms of mass.
why is this statement true?
Answer:
They are compounds made of the same two elements, but each contain different numbers of atoms. ... There are more hydrogen atoms in living organisms than any other atom, but oxygen is more abundant in terms of mass. Why is this statement true? Hydrogen atoms have a lower mass than oxygen atoms.
Answer:
The statement is true because there is more of the actual atom hydrogen in living organisms, as oxygen is more abundant in the world, but not in every living organism.
Explanation:
For example, there is more hydrogen in living organisms added up, but there is more oxygen in the world. If you add them all up, the mass of oxygen would be more then hydrgen, but more hydrogen in actual living organisms.

Which of the four molecules has the highest amount of stored energy? Carbon dioxide water oxygen glucose
Answer:
Glucose
Explanation:
Glucose has the highest amount of stored energy that the others because glucose posses more chemical bonds which can undergo rearrangement as a result of chemical reactions. When the bonds are rearranged there is release of energy meaning that the bonds in glucose consist of stored energy. Water, carbondioxide and oxygen does not have much chemical bonds compared to glucose, hence they don't have stored chemical energy.
