State whether it is a normal developmental phenomena or not, support your answer.Reflect on how chromosomal abnormalities in sex chromosomes during meiosis affects sexual development. Research other chromosomal disorders that occur due to errors that occur during meiotic cell division. Additionally, research whether there are treatment options available for these chromosomal disorders. Share and discuss the results of your investigation with your peers. include a reference.

The GP decides to request ultrasound imaging to check on the pregnancy. Describe why ultrasound is the imaging technique of choice to monitor foetal development in the womb. Describe how ultrasound can be used to provide diagnostic images in medicine. Highlight the role of sound for imaging and describe how sound is generated and received. Explain in detail which physical properties of human tissue is exploited by this technique. Describe the ultrasound technique that can be used to monitor blood flow and diagnose diseases that impact blood flow. Explain the physical principles underlying magnetic resonance imaging and provide three examples where it could be used to provided information not accessible with ultrasound. [9]Give typing answer with explanation and conclusion to all parts Consider the following scenario for your discussion board this week and answer the prompt that follows: Jeffrey is a 15-year-old boy who has been coming to your office for 5 years. At his yearly physical, you tell him that it is important that he perform a monthly testicular self-examination. When you attempt to explain to him how to perform the examination, he becomes embarrassed and does not appear to be listening to your instructions.

- There are 6 major events in fertilization. Discuss the process of fertilization or conception, with emphasis on the sperm-egg interaction. Proteins on the sperm plasma membrane bind to ZP3 molecules within the zona pellucida of the egg. Why is this event important? Zona binding triggers the acrosome reaction, in which the sperm plasma membrane fuses with the outer acrosomal membrane, causing exocytosis of acrosomal contents. What is in the "acrosomal content"? Acrosomal enzymes begin to dissolve a hole in the zona pellucida. This enzymatic degradation, accompanied by rapid sperm tail beating, moves the sperm through the zona. Where does the sperm intend to reach?During the organogenesis stage, several of the five essential developmental processes take place. Choose two of these essential processes and describe how and when they occur during the organogenesis stage. Be specific about the cells, tissues, and organs involved and the results.Mumps is a viral infection. The primary symptom of mumps is visible swelling of the parotid gland on either side of the face. However, the virus can also infiltrate the male reproductive system, causing the testes to atrophy. Some effects include oligospermia (low sperm count), azoospermia (no sperm in semen), and asthenospermia (reduced sperm movement). Research treatment options for reduced sperm movement. Describe one option that can be used to aid successful fertilization and explain why it helps.
