Afriend asks you why sea anemones are not placed in the phylum echinodermata. she says," sea anemones have radial symmetry, so they must be sea stars." "of course you are correct about the radial symmetry in both groups of organisms," you reply. select the best choice for the rest of your response. "however,

a. sea anemones are members of the phylum cnidaria and anyway, they are protostomes, not deuterostomes."
b. echinoderms are only radially symmetrical in their larval forms."

d. sea anemones and sea stars are both marines."
e. sea stars are mobile whereas sea anemones are mostly sessile.

Neelaredoxin is a 15-kda protein that is a gene product common in anaerobic prokaryotes. it has superoxide-scavenging activity, and it is constitutively expressed. in addition, its expression is not further induced during its exposure to o2 or h2o2 (silva, g., et al. 2001. j. bacteriol. 183: 4413–4420). which of the following statements best describes neelaredoxin synthesis? a-neelaredoxin is produced at all times; levels are constant even when exposed to o2 or h2o2.b-neelaredoxin is produced at all times; exposure to o2 or h2o2 increases expression.c-neelaredoxin is produced at all times; exposure to o2 or h2o2 decreases or prevents expression.d-neelaredoxin is only produced when there is exposure to o2 or h2o2.
