A) A sound wave
The other 3 create mutations, are cells are hit by sound waves all the time and experience no mutations because of it
Explanation:
Combine like terms.
-2y + 7y = 5y
-4 - 5 = -9
So the answer would be <u>5y - 9</u>

Answer:
Some plants can produce seeds without fertilization. Either the ovule or part of the ovary, which is diploid in nature, gives rise to a new seed. This method of reproduction is known as apomixis. An advantage of asexual reproduction is that the resulting plant will reach maturity faster.
Explanation:
Answer:
RNA-dependent RNA polymerase.
Explanation:
DNA polymerase I is present in E.coli that are responsible for the prokaryotic DNA replication. The DNA polymerase I was discovered by Arthur Kornberg. This enzyme is coded by the gene polA.
DNA polymerase I has the activites of DNA-dependent RNA polymerase, DNA-dependent DNA polymerase and RNA-dependent DNA polymerase. The RNA-dependent RNA polymerase is generally present in the reverse transcriptase in case of viruses only. RNA-dependent RNA polymerase catalytic site is not present in DNA polymerase I.
Thus, the correct answer is option (1).
