The correct answer is A. A sperm
Explanation:
Sperms are a type of reproductive cells that are essential for sexual reproduction. Sperms are male reproductive cells different from eggs that are female cells. Additionally, these can have flagella that allow them to move to reach the egg or be non-motile. In the case of human sperms, these have a flagella and also they contain 23 chromosomes; additionally, in this there is 1 allosome chromosome that defines sex and in males and therefore sperms can be either X or and 22 autosomes that refer to chromosomes not related to sex, this is also particular from sperms as eggs in humans can only have an X allosome. According to this, it is a sperm the cell that contains 22 autosomes and a Y chromosome.
Hope this helps! I added a second cladogram to help with any confusion because I can see how you got stuck with the first one :)
Bladder spinal reflex is the mechanism so you can
consciously void urine. There are receptors in the bladder that senses the
amount of urine collected. These are responsible for that ‘voiding urge’. The
higher the amount of urine collected, the greater the intensity of the signals.
Finally, when you get to the bathroom,
another set of nerves lets you consciously urinate so you can select which bathroom
stall is nice for peeing. Diabetes mellitus can damage nerves in the spinal
cord, including those involved in functioning of the bladder. Damage to the nerves
in the bladder spinal reflex arc is suspected if the patient suffers from
urinary retention – where the patient can consciously void urine but cannot
feel if the bladder is full.
