A negative tropism is when a plant grows away from stimulus
Answer: Option B) No, even though the DNA sequence changed, the sequence still codes for the same amino acid, so no change in phenotype will occur.
Explanation:
Since the triplet codon ACG codes for the amino acid threonine, so also ACA codes for threonine, the single base change of Guanine (in ACG) to Adenine (ACA) is insignificant due to the degeneracy of the genetic code.
Thus, the sequence still codes for the same amino acid, so no change in phenotype will occur
Answer:
B. Virus.
Explanation:
Hello.
In this case, since bacteria (A.) reproduce via asexual reproduction via mitosis and the animal (D.) and vegetal (C.) cells could reproduce via sexual or asexual reproduction depending on the organism, they do not need a host to start the replication of the DNA and therefore reproduce. In such a way, it is widely known that viruses need a host that facilitates the replication of their DNA or RNA (depending on the virus) since they only have their genetic information but they do not have neither the RNA nor the DNA polymerase that favor such process, that is why they need a host.

Neck length is what is going to change so that is the Independent Variable. The Dependent Variable is the Survival Rate.
Hope this helps
