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
Answers
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.

how do photosynthesis and cellular respiration form a cycle?
Answers
Answer:
The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
Explanation:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

O A. High humidity
B. Lower air pressure
C. Low humidity
D. Higher air pressure
Answers
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.

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?
Answers
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.

What would happen if the sedimentary rock was exposed to energy from the sun and then millions of years later to energy from Earth’s interior?
Answers
Answer:
They would become igneous rocks
Explanation:
If originally, sedimentary rocks are exposed to energy from the sun, no changes will occur to them.
One will hardly spot any difference in their mineralogical composition as such.
The temperature of the sun does not any significant alteration on earth materials. The heat from the interior has a very significant effect on rocks, especially sedimentary rocks. Heat from the interior can reach a staggering 6000°C which is more than enough to cause a metamorphic change in a body rock. In fact, at this temperature, igneous rock will be produced from the sedimentary rock.Igneous rock will be produced from the sedimentary rock if the sedimentary rock was exposed to energy from Earth’s interior for millions of years.
The temperature of the sun does not make any significant changes on sedimentary rocks.
The heat from the interior has a very significant effect on sedimentary rocks.Heat from the interior can reach upto 6000°C which is able to cause a metamorphic change in a rock.Therefore, igneous rock will be produced from the sedimentary rock if the sedimentary rock was exposed to energy from Earth’s interior for millions of years.

A motorcycle accelerates 3 m/s2 due to a force of 330 N. What is the mass of the motorcycle? Mass of motorcycle = _____ kg
Answers
Answer:
110 kg
Explanation:
Given
Acceleration (a) = 3m/s²
Force (F) = 330N
Required
Determine the mass of the motorcycle
This question is an illustration of Newton's second law and will be solved using:
Force = Mass * Acceleration
F = m * a
This above implies that force applied on the motorcycle is a product of its mass and its acceleration
Substitute values for F, and a
330N = Mass * 3m/s²
Make Mass the subject
Mass = 330N/3m/s²
Mass = 110kg
Hence, the calculated mass of the motorcycle is 110kg
Answer:

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
Answers
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.

Explanation:
En un experimento un floricultor cruzó plantas de flores púrpuras con plantas de flores blancas, los resultados obtenidos durante la primera generación fueron de un 100% de flores púrpuras, y en la segunda generación un 25% de flores serán de color blanco y el resto de color púrpura. Los genotipos de los parentales (P)
Answers
Answer:
Los genotipos de los parentales son:
- pp (homicigota dominate con flores púrpura)
- bb (homocigota recesivo con flores blancas)
Explanation:
Alelos:
p: púrpura y b: blanco
Genotipos parentales:
- pp: homocigota dominante (flores púrpura)
- bb: homocigota recesivo (flores blanca)
Cruzamiento parental: pp X bb
F1: 100% pb
Cruzamiento F1: pb X pb
F2: 25% pp (flores púrpuras), 50% pb (flores púrpuras) y 25% bb (flores blancas)
En este caso, el alelo que determina el color púrpura es dominante sobre el alelo que determina el color blanco. Es por esta razón que en la F1 todas las plantas heterocigotas exhiben un fenotipo con flores púrpura. En la F2 la proporción fenotípica será 1:2:1 (1 homocigota dominante, 2 heterocigotas y 1 homocigota recesivo), mientras que la proporción genotípica será 3:1 (3 plantas con flores púrpuras y 1 planta con flores blanca).
