Imagine you are lifting a box that weighs 60N. You must lift it to the top of this inclined plane. Your buddy suggests that you push the box up the inclined plane instead of Lifting it. How will the force change if you push the box instead of lifting it?

answer; ///i believe that the correct answer is (d); ///

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
