Answer: A the chromosomes from another parent cell were introduced
Explanation: A child is created when the male sex cell joins the female cell. If the male and female sex cells had the standard number of chromosomes, as is found in body cells then the zygote (baby) would have double that number of chromosomes. The number of chromosomes would keep doubling every generation. To avoid this doubling the parent's body cells split by miosis which halves the number of chromosomes and so when the sex cells join the total number of chromosomes is the same as that found in the parent's body cells.
The nurse should explain that during surgery,
an antibiotic prophylaxis is administered to prevent the incidence of surgical
site infection. The use of antibiotic before the procedure is just
one of many actions taken to help reduce the rate of wound infections.
Furthermore, the initial dose must be given most likely within 30
minutes before incision. Then, the next dose is at one to two half-lives of the
antibiotic, which is recommended for the duration of the surgery. Thus,
appropriate timing of dose is essential to the effectiveness of the antibiotic.
