In a dihybrid cross, if two heterozygotes (for both genes) are crossed, what will be the expected phenotypic ratios? (In the following order: dominant for both traits; dominant for the first trait and recessive for the second; recessive for the first trait and dominant for the second; recessive for both traits.) Group of answer choices

6:6:3:1

4:4:4:4

9:3:3:1

1:2:2:1

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.

that is true   : ) hope this you

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms

the answer is c. it will give up it's valence electron to the other atom.
