Answer:

"the presence in or introduction into the environment of a substance or thing that has harmful or poisonous effects."

In eukaryotic cells, the message from the DNA must be removed from the nucleus before it can be read and used to make proteins.
Crank

Answer:

The correct answer is A protein production can occur much faster in prokaryotic cell since the cell does not have to get the message stored in the DNA out of the nucleus.

Explanation:

protein biosynthesis or translation occur in both Prokaryotes and Eukaryotes.

                In prokaryotic cell both transcription and translation occur inside the nucleus but in case of Eukaryotic cell transcription occur in the nucleus whereas translation occur in the cytoplasm.

         In case of eukaryotic cell mRNA processing occurs which involves 5 prime capping, 3 prime tailing and splicing but in case prokaryotic cell no such processing occurs.

                  As a result protein production occur much faster in prokaryotic cell than that of eukaryotic cell.

Alenkasestr [34]

The two resulting populations will evolve and adapt differently over time to the different ranges as the conditions change in both ranges.

Their color, size, lifespan, and consumption choices may change with that.

After all of this takes place, you're left with 2 new breeds/species of butterflies.

Hope I helped :)
