how do poriferans and earthworms differ in their mobility

Poriferans reproduce asexually and sexually ,by hermaphroditic and produce eggs and sperm at different times. Explain in at least 3 well-written sentences. The worm expands part of its body, using a combination of hydrostatic pressure and its setae to hold that section in place against the soil. There's even a word for it: trioecious.

The body wall has two cellular layers, and unlike sponges, cnidarians have true tissues (Fig. And that causes, um, some potential detrimental impacts on corals which use calcium carbonate to build their skeletons. They have no appendages and no ability to make any movements, lacking muscle tissues. _______ includes three classes: Hydrozoa, Scyphozoa, and Anthozoa. Cnidarians have two basic body plans: ____(? As we learn about the different invertebrate phyla, we will be able to chart some of this history. 3.

Their name defines them as worms with many bristles because they have sensitive hairs on each segment of their body. Earthworms increase porosity by two mechanisms: (1) by creating permanent burrows, and (2) by improving soil aggregation.
