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...

Bio 100 Exam 3 (Jaeger UNLV) Questions and Answers 100% Pass **Evolution is defined as** any change in the phenotype of a population over successive generations due to genetic factors. **Common Descent with Modification entails** species undergoing modifications across generations. These changes can lead to the emergence of new, distinct species. **Species are** various types of organisms. Individuals within the same species share genetic similarities and can potentially interbre...
