1)While the Lophophorata (this groups includes worms and mollusks) are a well-recognized group, phylogenetic (family tree) studi
es do not yet agree on the identity of their closest relatives. True

The right answer for the question that is being asked and shown above is that: "TRUE; TRUE; TRUE" (1) While the Lophophorata (this groups includes worms and mollusks) are a well-recognized group, phylogenetic (family tree) studies do not yet agree on the identity of their closest relatives. (2)The marine flatworms (polycladids) are the smallest of the free-living flatworms, sometimes reaching lengths of 15 centimeters.

Animals use specific strategies to attract males/females in their species because for the mating process to happen, the animals must be attracted to one another so that they can continue with the certain circle of life.
Answer: because water is much more dense than air, tidal energy is more powerful than wind energy. Unlike wind, tides are predictable and stable. Where tidal generators are used, they produce a steady, reliable stream of electricity
