Hydrogen ions. Hydrogen ions are pumped across the membrane
during electron transport. They are giving around the membrane by ability of
energetic delivery. This establishes an electrochemical ability around the
membrane like the single responsible for the action of nerve cells. Nerve cells
use Potassium ions.
I think that the best answer is first one:
a) Trace the path that the sound waves travel as they enter the ear and proceed to the receptor cells for hearing, making sure to explain the process of transduction.
Answer:
I think that birds have different bill lengths because of their habitats and their diet.

The mRNA is then used to generate proteins by a process called translation which occurs in the cytoplasm. Transcription occurs in the nucleus because DNA cannot leave the nucleus.
