The parasympathetic nervous system is characterized by the location preganglionic neurons and the short postganglionic axons near the organs they innervate. The preganglionic neurons would originate in the spinal cord or the brainstem while the postganglionic neurons would lie outside the CNS.

Oxygen is the correct answer !
Answer:
The correct answers to the question are:
- The concentration of solute bathing the inner side of the plant cell membrane should be high.
- The concentration of solute bathing the outer side of the plant cell membrane should be low.
Explanation:
- Turgidity can be defined as a condition in which the cell membrane of the plants cells becomes completely extended as a result of which it pushes tightly against the cell wall.
- This happens when the cell takes up water from its environment and stores it in the vacuoles.
- Water enters to the inside of the cell by the process of Osmosis.
- Osmosis can be defined as the process by which molecules tend to move or diffuse from a region where its concentration is high to another region where its concentration is low, provided the two regions are separated by a semi-permeable membrane.
- In any region, the concentration of solute and and concentration of solvent bears an inverse relationship. This means that the region where the solute concentration is high, the solvent concentration is low and where the solute concentration is low, the solvent concentration is high.
- In the given question, as the cell takes up water from the surrounding into its vacuole to become turgid, so by the concept of osmosis, the concentration of water must have been high outside the cell and low inside the cell.
- Again by the inverse concentration concept of solute and solvent, the concentration of solute inside the cell should be more than the concentration of solute outside the cell.
The answer to this question would be: prostate glands
The term upper end is a bit ambiguous and it should be better to call it the proximal end of the urethra. The upper ends of the urethra, near the bladder, there is an organ called prostate. The prostate is a gland that only found in males as its function was to produce seminal fluid, make it a bit alkali.
