Arthropods - answerPhyla with greatest amount of diversity with 85% of animal spp 700 million years ago - answerWhen the first animals originated Porifera (sponges) - answerPhyla with no tissues, muscles, nerves, or specialized organs Choanocytes - answerFlow of water and food acquisition in sponges Amoebocytes - answerFound in sponges, these cells are mobile and perform numerous functions, including reproduction, transport of f...

1. Phylum Porifera - Answer-- sponges - loosely organized and lack tissues - multicellular with several types of cells - 8,000 species, mostly marine - no apparent symmetry - adults sessile, larvae free-swimming - water drawn through pores into spongocoel - flows out through osculum - choanocytes line spongocoel - mesohyl between choanocytes and epithelial cells - reproduce sexually and asexually 10. Phylum Nematoda - Answer-- roundwomrs - in nearly all habitats - over 20,000 specie...

What are the criteria of hydrostatic skeletons? - Fluid maintained at constant volume - container for fluid must be deformable - container for fluid is wrapped in muscle and connective tissue Any deformable, incompressible material maintained at constant volume can act as a hydrostatic skeleton What is the mechanical advantage for cylindrical hyrdostats As a cylinder of constant volume changes shape there is a non-linear relationship between its diameter length How to extend tentacles or arms...
