Replication of RNA genome in RNA virus does not involve proofreading. Thus RNA viruses have higher rates of mutation. So the correct option is B.
<h3>What is meant by proofreading? </h3><h3> </h3>
There are a variety of mechanisms in the cell to prevent mutations. Thus, permanent changes in the DNA sequence are prevented.
During the process of synthesis of DNA, DNA polymerases can analyse any mistake made during the synthesis and fix it. The majority of mispaired bases can be fixed by this process. It is called proofreading.
This process is not present in RNA and RNA polymerases. Thus RNA viruses appear to have higher rates of mutation compared to DNA viruses.
Therefore the correct option is B.

Answer:
Explanation:
For question 2 I think the answer is Endocytosis. 'Exo' means out and 'Endo' means in.
For question 4 I think it's A.
If you have ever played it, think of Agario. The bigger the molicule (or circle), the slower it moves.
I don't know about the others.
Hope this helps :)
Answer:
Fox squirrels feed mainly on hickory nuts and acorns, but also eat the fruit of tulip poplar, maple tree seeds, corn bordering woods, berries, bird eggs and fungi. Gray squirrels feed primarily on nuts, especially hickory nuts, acorns, beechnuts and walnuts.

Answer:
The correct answer is B. Carbon dioxide and water released by cellular respiration are used in photosynthesis.
Explanation:
Both photosynthesis and respiration are interconnected with each other because the product one process is utilized in another process.
In photosynthesis, plants use light energy to convert carbon dioxide and water into glucose and release oxygen.
6CO₂ + 6H₂O+ energy → C₆H₁₂O₆ + 6O₂
In respiration, the product of photosynthesis glucose and oxygen is converted into carbon dioxide, water, and energy.
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O+ energy
This shows that both processes are interrelated so the correct answer is B. Carbon dioxide and water released by cellular respiration are used in photosynthesis.
