Which idea best describes why the volume of water in earth’s oceans changes? large amounts of ocean water are lost to the mantle within rifts. new water is constantly added to earth’s oceans by space objects. ocean water is lost to the earth's atmosphere. ocean water is lost to space through evaporation.

Ocean water is lost to the Earth's atmosphere.

Explanation:

Ocean water is lost to the Earth's atmosphere, is the idea that best describes why the volume of water in Earth’s oceans changes.

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.

b. read the phase at the intersection of any given temperature and pressure.
