- How can we preserve animal reproduction?Sponges are considered to be animals because they are Multicellular, heterotrophic, have specialized cells and move at some point during their life. Multicellular. Heterotrophic and have specialized cells Multicellular, heterotrophic, have specialized cells and tissues Multicellular, heterotrophic, sessile, have specialized cells.What are relictual (plesiomorphic) features? Derived (apomorphic) features? Which organisms seem to have a larger percentage of relictual features—prokaryotes or eukaryotes? Algae or flowering plants? Amoebas or humans?
- Do tardigrades (water bears) have cell walls?When describing this experiment to your friends, they point out that rotifers are multicellular predators and thus cannot have been responsible for the earliest transition from single cell to multicellularity. Based on what you have learned in this lab and in the paper by Herron et al. 2019, what would be an informed response to this comment include? Select all that apply. Question 3 options: It is irrelevant that rotifers are multicellular in our study as some of the predators of small unicellular organisms are themselves unicellular, and predation, whether by a unicellular or multicellular organism, was all that was needed. Multicellularity evolved many times. While multicellular predators cannot have been responsible for the earliest transition from unicellular to multicellularity, they may have played a role in some of the later transitions which occurred after the evolution of animals. Using a multicellular predator is…Where do invertebrates fit into the evolution history of eukaryotes? Of animals?
