Most cnidarians are known to produce toxins. In fact, it has been claimed that one particular
species produces the most deadly of all toxins on the planet. What feature of this group most likely
evolved simultaneously with the evolution of these toxins? Selected Answer: A slow-moving or
sessile lifestyle in the adult Answers: Bilateral symmetry in the mobile larval forms Asexual
reproduction The medusa body form A slow-moving or sessile sffestyle in the adult Dipioblastic
design Question 21 0 out of 2.5 points Which of the following extremophiles might researchers
most likely use as a model for the earliest organisms on Earth? Selected Answer: An archaean
capable of surviving in the polar ice caps Answers: A bacterium found on another planet or moon
A bacterium capable of living at extremely high salinity An archaean capable of surviving in the
polar ice caps A bacterium that theives in a highly acidic environment An anaerobic archaean
