Practice question 4 Šperm cells that do not reach the egg, either flow back out of the vagina or are eliminated by macrophages found in the reproductive tract. By what process are macrophages able to take up sperm cells Based on your understanding of cellular organelles and their roles, what happens to a sperm cell once it is inside of the macrophage? Name 2 cellular functions that this will in turn support and briefly describe why/how?

Question: Regarding the events that take place in the complex process of spermatogenesis, which of the following statements is true: a.The sperm nucleus behaves like that of any other somatic cell, and remains quiescent until its replication during cell division, maintaining the RNAs. b.RNA transcription is continuous, and even increases as the process progresses, since the RNA content in the sperm will have a key relevance in early embryo development and is related to assisted reproduction outcomes. c.RNA transcription in the sperm does not contribute to embryo quality or reproductive success, since it is silenced, and the oocyte will be responsible for its contribution as well as its functionalities in the embryo. d.There is no RNA transcription in the later stages, but the mRNA content in the sperm that comes from previous stages of spermatogenesis will have a key relevance in early embryo development and has been related to the ability of the sperm to achieve a pregnancy.
