A C and G

Explanation:

Hi! I am a high school student so I might be wrong but from what I understand these seem to make the most sense. Well, A makes sense because there would be more weight to the ball because of the increase in the overall weight of the ball. C make sense because the more density the MORE likely the object is to SINK, and less density would mean the object is MORE likely to FLOAT. G makes sense because obviously if you added a weight to the ball in would make the ball sink due to the force of gravity pulling the heavier ball down. I hope this helps

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.
