(06.02 MC) You are leading an effort to reduce the formation of a dead zone in the Gulf of Mexico during the summer. You are tasked with selecting which compam
hired to help treat water runoff in the area. You provide both companies with identical samples of the water to be treated. The table below shows the re
company do you award the contract and why?

O I would choose company 1 because they decreased metals the least, and metals kill microbes
I would choose company 1 because they reduced nitrate and phosphate fertilizers the most and these fertilizers contribute to dead zone formation

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.

what's the

its probably to later but whats the question

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
