What are the functions of a nerve cell?The functions of a nerve cell are as follows:
It receives messages from all the different parts of the body. It plays an essential role in the transformation of messages to the brain. Nerve cells are also involved in commanding the different functions of the organs through the brain.So, if nerve cells deal with the electrical impulses and transformation of information and messages from one part of the body to the another, they definitely do not deal with the production of oxygen, division of more cells, and become a different type of cell.
Therefore, stopping sending signals to the brain is an appropriate function of the cell, once a nerve cell stopped functioning. Thus, the correct option for this question is D.

Researchers have been able to study the pathway of a secreted protein by tagging it with a fluorescent marker. Using this method, you would observe Fluorescence moving from the ER to which organelle
Answers
Answer:
I would observe fluorescence moving from the ER to the Golgi apparatus.
Explanation:
Once the protein leaves the endoplasmatic reticulum (ER), it is in a vesicle that fuses with the Golgi apparatus. The Golgi modifies and packs the protein to send it to its destination. In other words, the Golgi complex is the place where proteins go to be functional and be given a place either inside or outside the cell.
