Answer:
The correct answer is B. the two strands of DNA must separate.
Explanation:
DNA is a double-stranded structure. The two strands are joined together by the formation of hydrogen bonds between complementary nucleotides. So before the replication takes place these two strands must be separated.
The separation of DNA strand is accomplished by the action of a helicase enzyme which breaks the hydrogen bond between complementary nucleotides and separated the two DNA strands.
After separation, the DNA polymerase binds to separated DNA and replicating the DNA. So the right answer is B.
Explanation:
All cells have a plasma membrane, ribosomes,and DNA. The plasma membrane, or cell membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment. They both use ribosomes for producing proteins.
+sorry i made a mistake on the previous question. Prokaryotic cell doesn't have nucleus. I obviously didn't know the right meaning of this word bc im not a native english speaker

Answer:
the answer is volcanoes
Explanation:
The oceanic crust collides with the continental crust to form a convergent boundary. At the convergent boundary, the denser oceanic crust sinks under the lighter continental crust. The rocks of the oceanic crust reach very high temperatures of about 12,000°C, which is enough to melt the rocks. These molten rocks travel upward through cracks and crevices in the continental crust. They then erupt on the surface as volcanoes. Therefore, the feature expected to form at point X as the result of converging plates would be volcanoes.
