HURRY HELPPP Ashley was slowly adding 1 mL of a strong acid at a time to 30 mL of a strong base to measure the effect it had on the pH. What is the testing (independent) and outcome (dependent) variable of this experiment? What would a good control be?

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.

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.

wha is what i will use to get my free points

not necessarily. higher fitness requires the organism to be reproductive successful. for example, an organism at age 10 with 15 offspring is much more fit than an organism at age 15 with only 5 offspring.
