me: SCIENCE 5 EARCH ASSIGNMENT: Do a research on external and internal fertilization and answer the Venn Diagram. External Fertilization similarities Internal Fertilization
Answer (1)
Answer:External FertilizationDefinition: Fertilization occurs outside the female’s body.Common in: Aquatic animals such as fish and amphibiansProcess: Eggs and sperm are released into the water, where fertilization takes place.Environmental conditions: Dependent on suitable water conditions; sensitive to temperature and pH.Number of gametes: Typically produces a large number of eggs and sperm to increase chances of successful fertilization.Development: Often leads to external development of embryos (e.g., in water).Internal FertilizationDefinition: Fertilization occurs inside the female’s body.Common in: Terrestrial animals, including mammals, birds, and reptiles.Process: Male transfers sperm directly into the female reproductive tract, where fertilization occurs.Environmental conditions: Less dependent on external conditions; can occur in various environments.Number of gametes: Generally produces fewer eggs and sperm compared to external fertilization.Development: Often leads to internal development of embryos (e.g., in a uterus), providing more protection.SimilaritiesPurpose: Both processes aim to combine genetic material from male and female gametes to form a zygote.Involvement of gametes: Both involve the production and fusion of male and female gametes (sperm and eggs).Biological significance: Essential for reproduction in many species, ensuring the continuation of genetic lines.Venn Diagram Summary
