(a)

Summary Introduction

To determine: The dependent variable in the graph.

Introduction: Hemoglobin is an iron-rich protein present in the blood. This protein acts as a carrier of oxygen in the blood. Oxygen gets attached to the iron-rich protein in the blood and transported to a different part of the body.

Explanation of Solution

The given graph shows the effect of pH on the hemoglobin-oxygen binding. Oxygen level represents the X-axis, and the Y-axis represents the percentage of hemoglobin bound to the oxygen. In the given graph, the dependent variable is the percentage of hemoglobin bound O2.

(b)

Summary Introduction

To determine: The pH value that represents the higher concentration of hydrogen ion and also explains their nature.

Introduction: pH value can be defined as hydrogen ion concentration in the solution. The solution which has a higher concentration of hydrogen ion is considered acidic, and a solution with a lower concentration of hydrogen ion is basic.

(b)

Expert Solution

Explanation of Solution

The given graph shows three pH values that have a higher concentration of hydrogen ion are 7.2, 7.4, and 7.6. The solution which has a pH value less than seven are considered acidic, but in the above graph, the values which are the least basic have the higher acidic content. The pH value of 7.2 has a higher concentration of hydrogen ion. The pH value of 7.2 is more acidic than the other two pH values.

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.
