A24-year-old man has been stabbed in the throat, and has what appears to be significant blood loss. bleeding from the wound continues. he does not respond to your voice, and you can hear gurgling with each shallow breath that he takes. what do you do?

Well, first of all, that's a very harsh death. Second of all, I would just stand there, but that's me. So to your answer!

You should call 911 immediately and put pressure on the wound to stop the bleeding. You should also  make sure he's not choking on his own blood.

I hope that answers your question!

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.
