The number of bacterial cells that are present 3 hours after introducing 20 bacterial cells to the pasta salad, assuming that the generation time is 20 minutes. Concept introduction: Exponential growth involves a growth in the cell population by a factor of 2. These populations contain a high number of cells; therefore they are represented as exponents. When the exponential number and time graph is plotted, the line comes out to be straight, representing exponential growth. Doubling time is the time taken by a bacterial cell to form two daughter cells, after completing a fission cycle. It is also referred to as generation and is a constant process under favorable conditions. In bacteria, each doubling time leads to a doubling of their population. This process leads to an exponential growth in their population. Each exponent represents a generation in exponential growth.

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
