Place the steps of transcription in order:

1. rna polymerase attaches to the dna template

2. the mrna strand moves out of the nucleus

3. base pairing forms mrna

4. the dna strand separates

4. The DNA strand separates

1. RNA polymerase attaches to the DNA template

3. Base pairing forms mRNA

2. The mRNA strand moves out of the nucleus

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
