Several isolated haploid petite mutants and wild-type cells were mated with each other on complete media to form diploid cells. the diploid cells were then starved so they would go through meiosis and form haploid spores. the spores were grown on minimal media plates that contained glycerol as the only carbon source (so no fermentation could occur).

which of the following diploid cells would be able to produce haploid spores that could grow on the minimal media plus glycerol plates? select all that apply.

(a) segregational petite / wild type
(b) segregational petite / neutral petite
(c) segregational petite / suppressive petite
(d) suppressive petite / wild type
(e) suppressive petite / neutral petite
(f) neutral petite / wild type

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.
