Answer:
The correct answer is - 23 (haploid).
Explanation:
Each mature sperm cell is a gamete that is produced by the meiosis type of cell division. Meiosis is the cell cycle that produces four cycle with the half chromosome in number than that of the parent cell. Humans have 46 chromosomes in but as explained the sperm or the gamete have only of that which is 23.
The same goes for ovum which is form by the meiosis second process from oocyte which is basically the egg cell. Both sperm and the ovum fuse to fertilize.
Thus, the correct answer is - 23 (Haploid)

- The phrenic nerve is derived from the cervical plexus and receives innervation from the C3, C4, and C5 nerve roots. It is the longest branch of the cervical plexus.
Why does phrenic nerve supply diaphragm?
- The C3-C5 spinal nerves in the neck give rise to the phrenic nerve, a mixed motor and sensory nerve.
- The diaphragm, the main muscle of respiration, is exclusively controlled by the nerve, making it essential for breathing.
What organ does this nerve supply?.
- The jejunum receives both intrinsic and extrinsic nerve supply.
- The preganglionic parasympathetic and postganglionic sympathetic branches of the celiac plexus provide the autonomic extrinsic supply.
- These neurons go via branches of the major vessels from the mesentery into the jejunum.
What are the 4 types of nerves?
It is conventional, however, to describe nerve types on the basis of their function: motor, sensory, autonomic or cranial.
- Motor Nerves.

Answer:
The onset, and treatment of PTSD is no easy matter. In order for such a disorder to appear, which is later expressed with tremendous peaks of stress, crisis, behavioral problems, panic disorders, anxiety disorders, and many more debilitating conditions, a person must have experienced an event, or circumstance, that traumatically negatively impacted the correct psychological and emotional processes of the mind. In these patients, one the most common situations is that panic attacks and anxiety peaks happen particularly when the traumatic event, moment, or circumstance is remembered, and they are very good at remembering not just the moment itself, but all elements that surrounded that trauma. Also, they are able to make really clear connections and associations between those events and normal events in life that, when they appear, trigger the defensive responses of the mind.
The idea of administering a patient with PTSD with medication that would stop memory formation shortly after a traumatic event would not be a good idea simply because while the drugs focus on the chemical processes involved in memory formation, this procedure ignores that memory is much more than just chemicals in the brain. This has been show time and time again in research. Even with strong medication that basically generates amnesia, or trauma to the brain that may cause amnesia, it has been seen, and science cannot yet fully explain how, these patients may have partial, or total recovery of memories. And because the process of memory formation is still so misunderstood, and not all the factors involved are completely known, simply administering a drug that would stop the hormones that are believed to play a role in memory formation could become more of a problem for the patient. Also it is not being considered that amnesia causes even more stress in patients, as somehow the brain still recognizes that there is information present, but cannot simply bring it to concious awareness.
