The definition of pH of a solution. Introduction: The pH of a substance can be acidic, basic, or neutral. The acidic substances have a pH below 7, for example: lemon juice, vinegar, and so on. The basic substances have a pH above 7, for example: baking soda, soap solutions, and so on. The neutral substances have a pH near or equal to 7, for example: pure water.

Summary Introduction

To determine: The definition of pH of a solution.

Introduction: The pH of a substance can be acidic, basic, or neutral. The acidic substances have a pH below 7, for example: lemon juice, vinegar, and so on. The basic substances have a pH above 7, for example: baking soda, soap solutions, and so on. The neutral substances have a pH near or equal to 7, for example: pure water.

Summary Introduction

Introduction: The pH of a solution negatively corresponds to the number of H⁺ ions present. When the number of H⁺ ions present is low in number, the pH becomes high. When the number of H⁺ ions present is high in number, the pH becomes less. When there are no H⁺ ions present in the solution, the pH remains neutral.

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.
