LIFE SCIENCE

Detailed explanation-1: -Members in the kingdom Animalia can reproduce sexually or asexually. Sexual reproduction involves two parents, and their gametes must fuse to reproduce an offspring. Asexual reproduction results in new organisms without the fusion of gametes.

Detailed explanation-2: -Asexual reproduction in animals occurs through fission, budding, fragmentation, and parthenogenesis. Sexual reproduction may involve fertilization inside the body or in the external environment.

Detailed explanation-3: -Echinoderms exhibit a form of asexual reproduction known as regeneration. In this form of asexual reproduction, a new individual develops from a part of another.

Detailed explanation-4: -Sexual reproduction occurs in a variety of ways in animals. In some species, such as fish, the male releases sperm over the eggs after the female has laid them. In other species, such as birds and most mammals-including human beings-the male releases sperm into the female reproductive tract.

Detailed explanation-5: -Animals can reproduce both by sexual as well as asexual means. Simple animals like Hydra, reproduce asexually by the process of budding. Some animals like tapeworms can reproduce both asexually as well as sexually. Higher and more complex animals like birds and mammals can reproduce only by sexual means.
