Which was concluded by Mendel as a result of his genetic research? A. Polyploidy can be beneficial in agriculture
B. Factors for different traits are inherited together as a matched pair
C. Factors for different traits are inherited independently of one another
D. Meiosis occurs in two steps, meiosis 1 & meiosis II

C. Factors for different traits are inherited independently of one another.

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.

the answer would be 3
