Both oysters and squid are mollusks. Why is an open circulatory good for oysters, but not for squid? Oysters are filter feeders and squid are carnivores
Oysters do not move around, but squid are very active
Oysters have higher O2 demands than squid
Squid live in waters with lower O2 levels than oysters

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

hello

answer: collecting information/data

reason: the student is going around and asking people questions to collect data

i hope this
