By what type of cell division do animals produce gametes?arrow_forwardSponges are also found in freshwater, though not as numerous as the marine varieties. One example of this group is Spongilla, which can grow in many different morphs. Spongilla and other freshwater sponges have developed specialized reproductive cells known as gemmules, allowing them to survive harsh environmental conditions.

- what are ciliates?arrow_forwardChoanoflagellates have collagen and the same genes coding for cell communication and adhesion that present in multicellular animals with bodies. Which best explains what this reveals regarding the evolution of multicellular bodies in animals? A) All of the genetic machinery and all of the body building materials (or similar precursors) evolved only after the appearance of multicellular bodies. B) The genetic machinery and some of the same body building materials (or similar precursors) are present in single-celled organisms, thus natural selection could use these for the evolution of multicellular bodies. C) That multicellular bodies evolved only once in evolutionary history, and it was within animals because collagen was present, along with the genetic machinery necessary for cell adhesion and communication. D) None of the above.arrow_forwardwhat are opiods and how does it works on the body?arrow_forward
