Answer:
The wavelength of any wave with a constant speed is inversely proportional to its frequency, because as something vibrates more frequently, there is less time between one vibration and the next. Each complete vibration is one wavelength, so if there is less time, it can only go a shorter distance.
Explanation:
Answer:
D. The site of transcription is within the nucleus
Explanation:
this is because the process of DNA is converted into RNA
This requires a protein called RNA polymerase. It will copy certain regions of DNA and convert them into RNA (this occurs in the nucleus) and then this RNA goes to the cytoplasm, where it will be translated into a protein.
Therefore, its D.
