The reason that the normal biota of GI tract seems to include a lot of disease-causing organisms. Introduction: Gastrointestinal tract or digestive tract is responsible for ingesting and digesting food, absorbing nutrients, and eliminating waste. The alimentary canal is a passage through which the food passes in our body. It includes mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus.

The reason that if microbiota are “normal” then why they are called potential pathogens.

Introduction:

The human body is occupied with various non-pathogenic normal microbiota, which prevents the entry of pathogenic microbes. For example, the normal microbiota of Lactobacillus and Staphylococcus among others prevents microbial infection in different body regions.

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.
