Lightning bugs contain a gene that creates a protein known as luciferin, which makes them bioluminescent (glow). If the researcher replaced genes Z, Y, and A of the lac operon with the gene for luciferin, how would this affect the bacterium? * 1) The bacterium would glow when it is fed milk.
2) The bacterium would glow when it is exposed to light.
3) The bacterium would not glow since the lac operon has been mutated.
4) The bacterium would not glow since the bioluminescence gene is from a different species.

Read this summary of a scientific theory: "cells are the most basic structural and functional units of life. all living organisms are made up of one or more cells. all cells that are alive in the world today came from pre-existing cells." which of the following would require this theory to be modified? -a.) a survey finds that a majority of people believe viruses carry out the basic processes of life. -b.) a prominent scientist says she feels strongly that one day the theory will be challenged by life on other planets. -c.) the dna of unicellular and multi-cellular organisms is shown to have many fundamental similarities. -d.) scientific observations show that microscopic organisms living in the deep ocean are not made up of cells.
