Use the sum rule to predict the fraction of offspring from an Aa×Aa cross that will have the dominant phenotype (AA or Aa genotype). Hint: In anyone for those fertilization event, only one of these three possibilities can occur (they are mutually exclusive). Figure out how many outcomes could produce and offspring with a dominant allele. Thank you so much!

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.

answer: 21

step-by-step explanation:

divide 630 by 30. 30 goes into 630 21 times

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
