Which of the following best describes the relationship between the nucleolus and ribosomes within a cell? Nucleoli house ribosomes until they are needed by the cell, after which they exit the nucleus and enter the Golgi apparatus to form proteins.
Proteins and rRNA assemble into ribosome subunits inside the nucleolus, after which the subunits leave the nucleus and combine to form ribosomes.
Ribosomes are manufactured in the cytosol, after which they enter the nucleolus and carry out protein synthesis.
Ribosomes break down the nucleolus so that DNA can enter the cytosol, after which proteins transcribe DNA into mRNA chains.

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
