Age structure would help scientists determine if the problem exists with young or old dolphins.

The age structure shows the distribution of the ages of the individuals in a population. This not only shows the type of change taking place in the population (increasing, decreasing or staying the same) but also is able to help us relate problems to ages. By determining the which age group is more stressed, the scientists will be able to narrow down the causes of the stress and create more accurate hypotheses.

The letter X in the diagram below represents what enzyme used in the process shown?

Anvisha [2.4K]

Answer: Option D. RNA polymerase.

Explanation:

Transcription is the process which is used to produce RNA from a DNA template.
The enzyme involved in the process of transcription is RNA polymerase which is responsible for separating the DNA strands and making an RNA which is complementary to the DNA.
RNA polymerase joins the nucleotides in the newly formed RNA strands by utilizing the energy released from the cleavage of the additional phosphate bonds that are removed by it.
The RNA polymerase dissociates from the DNA only after the process of transcription is complete.
