In the event of a mismatched nucleotide , which molecule is able to backtrack , "proofread , " and correct the nucleotide sequence ?
A. DNA Proofreadase
B. DNA Polymerase
C. DNA Helicase
D. DNA Primase
Answer:
The molecule that is able to go back and correct an error in the DNA nucleotide sequence is DNA polymerase (option B).
Explanation:
DNA polymerase is not only the enzyme that contributes to the polymerization of a new DNA strand during the replication process, but it can also correct errors in synthesis, such as when a mismatched nucleotide is placed.
Once an error has been detected during synthesis, the DNA polymerase —acting as a 3'-5'- exonuclease— reverses the process, the direction of synthesis, to correct the error which in this case is the mismatched nucleotide.
The other options are not correct because:
A. DNA proofreadasa does not exist.
C. Helicase breaks the hydrogen bridges that bind the nucleotides allowing the separation of the DNA strands. In some cases, it also acts as a DNA repairer
D. DNA Primase is responsible for the synthesis of primers.
The molecule that is able to get back to the correct the errors in the DNA is DNA Polymerase.
The polymerase is a member of the family of enzymes which synthesis the DNA molecule and forms triphosphate. They are essential for the replication of the DNA.Hence the option B is correct.

???usually means clear weather because stable air is sinking.
O A. High humidity
B. Lower air pressure
C. Low humidity
D. Higher air pressure
High air pressure usually means clear weather because stable air is sinking. The correct option would be D.
High air pressureHigh air pressure usually causes the sky to be clear.
This is because high air pressure causes the air at the lower atmospheric level to sink down towards the earth.
This is unlike low air pressure. It brings a cloudy sky along with precipitation.

a.
An environmental contingency plan is important to assess the effort required to make environmental changes.
b.
The effects of environmental changes cannot be determined with certainty, so contingency plans are necessary to effectively deal with unexpected changes.
c.
New environmental conditions cannot be developed without the existence of an environmental contingency plan.

Answer:
B!!! The effects of environmental changes cannot be determined with certainty, so contingency plans are necessary to effectively deal with unexpected changes.
Explanation:
According to the research, contingency plans are necessary to effectively deal with unexpected changes.
What are contingency plans?It is a type of preventive, predictive and reactive plan that allows minimizing the possible risks that can negatively affect an activity and deal with unexpected changes.
It presents a strategic and operational structure that will help control an emergency situation and minimize its negative consequences of environmental changes.
Therefore, we can conclude that according to the research, contingency plans are necessary to effectively deal with unexpected changes.

What cell membrane structure allows water-soluble materials to be passively transported to the cytoplasm?
A. Endocytosis vesicles
B. Carrier proteins
C. Hydrophilic phospholipid tails
D. Golgi complex vesicles
Answer:
B. Carrier proteins
Explanation:
Water-soluble materials, such as glucose, amino acids, and ions, need help to cross the membrane because they are repelled by the hydrophobic tails of the phospholipid bilayer. The tails are not hydrophilic.
Endocytosis vesicles are an example of active transport, they require energy to allow large molecules to be taken into the cell through a system of vesicles.
Golgi complex vesicles deliver proteins and other macromolecules outside of the cell from the inside.
Carrier proteins can participate in both active and passive transport across cell membranes. For example, carrier proteins with channels can help molecules cross the membrane passively.

Which of the following must occur before DNA replication can take place?
Answer:
Before replication can occur, the length of the DNA double helix about to be copied must be unwound. In addition, the two strands must be separated, much like the two sides of a zipper, by breaking the weak hydrogen bonds that link the paired bases.

How do human beings negatively affect the carbon cycle?
Human beings burn fossil fuels, which contribute carbon dioxide to the atmosphere.
Human beings conserve resources, which decrease resources for the carbon cycle.
Human beings mine resources, which increases the amount of oxygen available to the carbon cycle.
Human beings use carbon-based pencils, which decreases the amount of carbon dioxide in the atmosphere.
Eww
Answer:
Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. ... This extra carbon dioxide is lowering the ocean's pH, through a process called ocean acidification.

question one: why do stars change very little while they are in the main sequence stage?
question two: why does a main sequence star eventually grows in size to become a red giant?
Answer:
Q1 As the main sequence star glows, hydrogen in its core is converted into helium by nuclear fusion. When the hydrogen supply in the core begins to run out, and the star is no longer generating heat by nuclear fusion, the core becomes unstable and contracts.
Q2When stars first begin to fuse hydrogen to helium, they lie on the zero-age main sequence. ... The core of a red giant is contracting, but the outer layers are expanding as a result of hydrogen fusion in a shell outside the core. The star gets larger, redder, and more luminous as it expands and cools.
