Once the bacteria reach the stationary phase , it stops to grow due to loss of nutrient availability. Even when some bacteria are transferred to fresh medium, no cell growth is seen, since the bacteria as lost its viability to grow. Yet, some microbiologists suggest that the bacteria are temporarily unable to grow. The microbiologists suggest two hypotheses (Viable but nonculturable and programmed cell death) to for this condition of the bacteria.

Question

Definition Definition Phase during which the number of bacteria cell deaths gradually equals the number of viable or actively dividing cells due to decreased reproduction rate. Microbes utilize all nutrients present in the growth medium to multiply during the growth of the bacterial population, which results in the deposition of waste matter, toxins, and inhibitory compounds in the media. This changes media conditions, such as temperature and pH, creating an unfavorable environment for bacterial growth. Here, the growth rate becomes stabilized.

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.

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.
