Scientists are trying to engineer non-legume crop plants, such as corn, wheat, and rice, to form symbiotic relationships similar to the legume-Rhizobium relationship. But this has proven to be a very difficult task. At each step of nodule formation, plant genes must be expressed that enable the plant to respond appropriately to the bacteria. For a non-legume plant to form a symbiotic relationship with rhizobia, it would need to be engineered with the right genes and then express those genes at exactly the right time. In this activity, you will identify the steps of nodule formation in the legume-Rhizobium relationship. In addition, you will indicate what the products of genes added to a non-legume plant would need to do in order to carry out each step.

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.
