- Describe the differences in the anatomy and physiology of the male reproductive system in the owing species: dog, cat, horse, cow, small ruminants and pig. Illustrations may be utilized. Describe the structure of a sperm cell. matai ebu What is the difference between sperm and semen? o cac coas 20mod o sbobni alemis ofamob ni slbys uoee erb to 2025de srt admcsReproductive modes can be defined based on energetic provisioning (lechithotrophy vs. matritrophy) or birth style (ovipary vs. vivipary). Reproductive modes related to birth style mostly fall into clear categories of energetic provisioning. Define the above four reproductive modes based on energetics and style that make them distinct. Be sure to mention WHEN the relevant events related to each occur. Finally, explain why the birth style of ovovivipary less clearly falls into any one of these categories...IDENTIFY: A specialized receptive structure that guides the male gamete for fertilization in the genus Polysiphonia.
