One similarity between DNA and mRNA is that they both . pls help !!!

B) Both contain genetic codes based on sequences of bases

Explanation:

DNA chemical bases are ATGC, while mRNA chemical bases are AUGC. Uracil replaces Thymine in mRNA, so your answer (option C) is incorrect. However, they are similar in that mRNA carries genetic code from DNA in a cell's nucleus to ribosomes, while DNA contains the genetic information for development and function of living things.

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.

acceleration= v2-v1/t so 8m/s-3m/s / 3s =to 8/3 or

2.67 m/s^2
