The most vocal reptile ARE THE CROCODILES.
Crocodiles use different types of calls, smells and water behavior to communicate with one another. Scientists have discovered that some species of crocodiles can pass across up to twenty messages using sound alone. The sounds made can be used to signify threat, distress or it can be used to attract others for courtship purpose. Crocodiles also communicate through smells and through water behaviors.
Adaptations shouldn’t end up causing difficulties for the animal so that eliminates options A and D. Option B can be eliminated because a long beak more than likely wouldn’t help a bird hide from predators, if anything it could make it stand out more. So, the answer is C
Answer:
Option (A).
Explanation:
Epigenetics may be defined as the study of the heritable phenotype changes that do not change the sequence of DNA. The gene activity or gene expression changes in epigenetics. Environment may also brings the changes in gene expression.
The change in phenotype of the individual must be inherited in epigenetic changes. The chromatin must be modified but the nucleotide sequence remains unaltered in epigenetic changes.
Thus, the correct answer is option (A).
