There are differences between Eukaryotic and Prokaryotic cells. This difference is considered to be the most important distinction between groups of organisms.
A Prokaryotic cell does not contain a nucleus. It only contains one chromosome and is a single-celled organism. It was the only form of life on earth for millions of years. Examples of a Prokaryotic cell are the different types of bacteria present today.
A Eukaryotic cell contains a nucleus; more than one chromosome and is typically a multi-celled organism. <span>Both plant and animal cells are eukaryotic cells.

Answer:
C) It has a long preganglionic fibers
Explanation:
Peripheral nervous system (PNS) is the nervous system that contains nerves and ganglia outside the central nervous system (CNS). PNS is divided into:
- somatic (voluntary) nervous system-controls the movements of the skeletal muscles
- autonomic (involuntary) nervous system-controls the smooth muscles and glands and thus it is the regulator of the major body functions. It is subdivided into tree groups:
- sympathetic ("fight and flight") system-responsible for stressful and active situations (but also in normal conditions);contains short preganglionic fibers and long postganglionic fibers.
- parasympathetic ("rest and digest") system-opposite to sympathetic, responsible for the maintenance of body's activities at rest.
- enteric nervous system-controls the function of the gastrointestinal tract.
Answer:
The correct answer is - option C. electrogenic ion pumps
Explanation:
The CFTR protein which acts as the chloride ion Channel this Chanel is belongs to the Electrogenic pumps. These are also is categorize as the ABC Protein channel.
Electrogenic pumps are primary active transporters that hydrolyzes the ATP and the produced energy is used to transfer ions (cl ion in this case) across the membrane to generate the gradient across the membranes.
Thus, the correct answer is - option C. electrogenic ion pumps.
