Summary Introduction

To explain: The conversion of square meters into square feet and the calculation of area of the small intestine in square feet.

Introduction: Small intestine is an organ of the alimentary canal and is divided into three parts. The duodenum is C-shaped, first part that connects it with the stomach. The jejunum is a highly coiled portion in the middle, and ileum connects the small intestine with the large intestine.

Explanation of Solution

The length of the small intestine is approximately 4.5 m. However, the surface area of the small intestine increases because of the presence of finger-like projections called villi and microvilli. The surface area of small intestine is around 300 m2.

The conversion of square meters into square feet is as follows:

1meter=3.28084feet(1meter)2=(3.28084)2feet(1meter)2=10.7639~10.764feet

Since the surface area of the small intestine is 300 m2, the surface area in square feet will be calculated as follows:

Surfacearea(insquarefeet)=10.764×300squarefeet=33229.2squarefeet

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.
