Answer:
The best answer to the question: Which of the following statements is true, would be, D: the 16 cell stage through 100 cell stage is called the Zygote.
Explanation:
The topic of human fertilization, the process by which an oocyte and sperm join together to form a new human being, is pretty complex. The first thing that must be kept in mind about this process is: first, it is only the oocyte that has been arrested in Meiosis II, which will be completed once fertilization occurs; the sperm is a mature gamete, and has completed its Meiosis stages by the time it fertilizes the egg. Second, Meiosis I is completed in the oocyte, it is Meiosis II, which is completed upon fertilization. Sperm is produced on a daily basis by a man´s testes after puberty and eyaculation can come from both testes at the same time, or from one of them. However, the one statement that is true, is the last one: a zygote is the first name that the newly formed human being receives as its cells begin to replicate through mitosis, while it travels towards the endometrium, where it will implant. At this stage, the mitotic divisions will render between 16 to around more than 100 cells.
