Answer:Volcanic eruptions are very dangerous events.
Explanation:Models represent objects, events, and processes in the real world.
Models are often used when an object, event, or process occurs too slowly or too quickly; is too small or too large; is too complicated or too dangerous.
Volcanic eruptions produce both molten lava and poisonous gases. Therefore, eruptions can be very dangerous. Many volcanologists have lost their lives while observing volcanic eruptions.
Answer:
The mRNA goes after it is produced is made messenger RNA (mRNA) is a single-stranded RNA molecule that is complementary to one of the DNA strands of a gene. The mRNA is an RNA version of the gene that leaves the cell nucleus and moves to the cytoplasm where proteins are made.
Explanation:
mRNA formed in the nucleus is transported out of the nucleus and into the cytoplasm where it attaches to the ribosomes. Proteins are assembled on the ribosomes using the mRNA nucleotide sequence as a guide. Thus mRNA carries a “message” from the nucleus to the cytoplasm.
